History & the ISI Doctrine
Pakistan's relationship with jihadist groups as instruments of state policy began in earnest in the late 1970s, when General Zia ul-Haq — who had seized power in a 1977 military coup and hanged elected Prime Minister Zulfikar Ali Bhutto — launched a systematic programme of Islamisation of Pakistani society and state institutions. Zia's dual project served both domestic and strategic purposes: Islamisation consolidated his political authority by aligning the state with Pakistan's powerful religious establishment, while the ISI's cultivation of Afghan mujahideen groups — funded by the CIA and Saudi Arabia in Operation Cyclone — positioned Pakistan as the indispensable pivot of the anti-Soviet Afghan jihad and dramatically expanded the ISI's institutional power and external resources.
The doctrine of "strategic depth" — articulated most explicitly by General Mirza Aslam Beg and successive ISI chiefs — holds that Pakistan requires a compliant, Pakistan-friendly government in Afghanistan as a buffer against encirclement by India, and that jihadist proxies operating in Indian-administered Kashmir provide Pakistan with asymmetric leverage against a conventionally superior adversary without triggering a conventional war response. This doctrine has remained the operational foundation of ISI policy for over forty years, surviving repeated Pakistani pledges to Western partners to dismantle it, surviving the post-9/11 US alliance that flooded Pakistan with counter-terrorism funding, and surviving the Taliban's ultimate return to power in Afghanistan in 2021 — an outcome that ISI had been working toward throughout two decades of nominal cooperation with the US-led mission.
"Pakistan has been simultaneously the arsonist and the fire brigade. It has used every rupee of American counter-terrorism aid to fund the very groups it was being paid to suppress."
Bruce Riedel, Brookings Institution / former CIA, 2014The ISI's management of its jihadist portfolio has been characterised by a consistent distinction between groups it considers strategically useful — the Afghan Taliban, the Haqqani Network, Lashkar-e-Taiba, and Jaish-e-Mohammed — and groups it considers domestically threatening, primarily the Pakistani Taliban (TTP). This distinction has been the source of Pakistan's most blatant double-dealing with Western partners: Islamabad has selectively cooperated against groups that attacked Pakistani targets while actively protecting those directed against India and Afghanistan, a policy that senior US officials have described repeatedly in classified assessments that have since been leaked or declassified. The 2011 discovery that Osama bin Laden had been living in Abbottabad — 800 metres from the Pakistan Military Academy, in a compound that Pakistani intelligence had almost certainly monitored — crystallised the fundamental nature of Pakistan's enabling posture in a single, undeniable fact.
Pakistan's nuclear weapons programme provides the structural foundation of its immunity from accountability. No state — not the United States, not India, not the international community collectively — has been willing to press Pakistan to the point of regime or state destabilisation, given the consequences of a nuclear-armed state's collapse or the risk of nuclear weapons falling under jihadist control. Pakistani military planners have understood and exploited this calculus with extraordinary sophistication for decades, using the implied threat of state fragility and nuclear insecurity as leverage to extract aid, avoid sanctions, and escape the consequences of documented jihadist sponsorship that would result in designation if applied to any non-nuclear state.
Timeline
-
1977–1988General Zia ul-Haq seizes power and launches the Islamisation of Pakistani state institutions. The ISI, funded by CIA and Saudi Arabia through Operation Cyclone, trains and arms Afghan mujahideen against the Soviet occupation — establishing the template of ISI-managed jihadist proxy warfare and creating the institutional networks, funding channels, and ideological infrastructure that will sustain Pakistani jihadist sponsorship for decades.
-
1989–1994Soviet withdrawal from Afghanistan. The ISI continues backing favoured mujahideen factions — particularly Gulbuddin Hekmatyar's Hezb-e-Islami — in the subsequent Afghan civil war. ISI simultaneously expands its support for jihadist groups operating in Indian-administered Kashmir, establishing Lashkar-e-Taiba and Jaish-e-Mohammed as primary instruments of asymmetric pressure on India. Both groups are funded, trained, and operationally guided from Pakistani soil with ISI oversight.
-
1994–2001The ISI is the primary external patron of the Taliban as they rise from obscurity in Kandahar to seize control of Afghanistan by 1996. Pakistan, Saudi Arabia, and the UAE are the only three countries to formally recognise the Taliban government. ISI advisers are embedded with Taliban military units; Pakistani volunteers fight alongside Taliban forces. Al-Qaeda operates training camps in Taliban-controlled Afghanistan with Pakistani knowledge.
-
2001Following 9/11, Pakistan reverses its Taliban recognition under intense US pressure and becomes a nominal US counter-terrorism partner — receiving $600M in immediate payments and billions more in subsequent years. However, ISI simultaneously facilitates the escape of Taliban leadership across the border into Pakistani territory, where the Quetta Shura (Taliban senior leadership council) reconstitutes itself under ISI protection in Quetta, Balochistan.
-
2001–2011Pakistan receives over $18B in US counter-terrorism assistance while the ISI maintains active relationships with the Haqqani Network — described by Chairman of the Joint Chiefs Admiral Mike Mullen as a "veritable arm of Pakistan's ISI" — and provides sanctuary to Taliban leadership in Quetta and Peshawar. Multiple US intelligence assessments document ISI tip-offs to Taliban commanders ahead of planned US operations. The US-Pakistan alliance is characterised by what CIA directors privately describe as systematic Pakistani double-dealing.
-
2008Mumbai attacks: Lashkar-e-Taiba operatives conduct a four-day siege across 12 locations in Mumbai, killing 166 people including 6 Americans. Investigation by Indian and US authorities documents ISI involvement in the planning and support of the attack. Pakistani-American LeT operative David Headley later testifies to ISI's direct role. Pakistan refuses to extradite the attack's planner, Hafiz Saeed, who continues to operate openly in Pakistan for over a decade.
-
2011US Navy SEAL Team 6 kills Osama bin Laden in a compound in Abbottabad, 800 metres from the Pakistan Military Academy. Pakistani officials claim ignorance of bin Laden's presence — a claim regarded with profound scepticism by US and allied intelligence services. Pakistan arrests CIA informants who helped locate bin Laden. The ISI chief is summoned to parliament but faces no accountability. US-Pakistan relations reach their lowest point since 9/11.
-
2017–2022Pakistan is placed on the FATF financial crime grey list in 2018, citing systemic failures to prosecute terrorism financing. Hafiz Saeed — designated a global terrorist by the US with a $10M bounty on his head — is arrested in 2019 after years of operating freely, but prosecuted only on minor charges in domestic courts. Pakistan is finally removed from the FATF grey list in October 2022 after implementing minimum technical compliance measures, despite persistent concerns about strategic policy change.
-
2021Taliban seize Kabul on 15 August, completing their return to power with remarkable speed as the US-backed Afghan government collapses. Pakistani Prime Minister Imran Khan describes the Taliban takeover as Afghans having "broken the chains of slavery." ISI chief General Faiz Hameed visits Kabul within days of the Taliban's seizure of power. Pakistan's twenty-year strategy of sustaining Taliban sanctuaries while nominally cooperating with the US mission achieves its ultimate objective.
-
2022–2025The Afghan Taliban's return to power emboldens the Pakistani Taliban (TTP), which launches a wave of attacks inside Pakistan — killing hundreds of Pakistani soldiers and civilians. Pakistan conducts airstrikes on Afghan soil, straining relations with the Taliban government it spent two decades cultivating. The ISI's strategic depth doctrine produces a blowback crisis as the same jihadist infrastructure it built to project power outward begins directing violence inward. Pakistan remains on an IMF bailout programme and faces a deepening economic and political crisis.
Strategy & the ISI Enabling Architecture
Pakistan's enabling doctrine is military-institutional rather than ideological in the manner of Iran or Turkey. The ISI's jihadist proxy strategy was not born from religious conviction but from a cold strategic calculation: that non-state armed groups directed against India and Afghanistan provide Pakistan with asymmetric leverage it could never achieve through conventional military means, at a cost — in blood and treasure — that can be partially exported to the groups themselves and to the communities they operate in across the border.
The ISI manages its jihadist portfolio through a system of selective toleration and directed sponsorship that has proven extraordinarily difficult for Western partners to penetrate or disrupt. Groups are maintained on a spectrum from full operational partnership (Haqqani Network, Lashkar-e-Taiba) through tolerated presence (Afghan Taliban, Jaish-e-Mohammed) to actively suppressed (TTP, IS-K). The ISI's ability to modulate this spectrum — cooperating selectively against the groups that threaten Pakistan domestically or that the US is most urgently focused on in any given year — has allowed it to maintain the fiction of a counter-terrorism partnership while sustaining the strategic relationships that matter.
"The Haqqani Network acts as a veritable arm of Pakistan's Inter-Services Intelligence agency. With ISI support, Haqqani operatives plan and conduct organised attacks against Afghan and US forces in Afghanistan."
Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff, US Senate testimony, September 2011Pakistan's civilian government is, in the most meaningful operational sense, not in charge of the jihadist portfolio — the military and ISI are. This has created a structural disconnect that has repeatedly frustrated Western diplomacy: Pakistani prime ministers may sincerely pledge to dismantle jihadist infrastructure and be unable to deliver, because the ISI conducts its proxy relationships as a sovereign military prerogative that civilian governments cannot override without triggering a coup or a destabilisation campaign. The ISI's demonstrated willingness to remove civilian governments it dislikes — as with Imran Khan in 2022 — reinforces this structural reality. Pakistani democracy operates within limits set by GHQ Rawalpindi.
The nuclear shield is the final and most consequential element of Pakistan's enabling architecture. Pakistan tested nuclear weapons in 1998 and has since built the world's fastest-growing arsenal, with an estimated 170 warheads and delivery systems targeting India at multiple ranges. The implicit calculus — that pressing Pakistan too hard risks state instability in a nuclear-armed country with documented jihadist networks — has been internalised by every US administration, every Indian government, and every international body that has confronted Pakistan's enabling activities. It is, in the most literal sense, a get-out-of-designation-free card that no other state in the IFC library possesses.
Key Proxy & Support Relationships
The ISI maintains documented sponsorship, sanctuary, or operational freedom relationships with a range of jihadist groups whose activities span Afghanistan, India, and the broader regional theatre.
Documented Enabling Actions
Pakistan's enabling activities span four decades and multiple theatres — from the creation of the Afghan mujahideen infrastructure in the 1980s to the sustained Taliban sanctuary that enabled their return to power in 2021, to ongoing ISI support for anti-India jihadist groups despite repeated international pressure.
Affected Populations & IFC Desks
Pakistan's jihadist sponsorship has produced catastrophic harm across South and Central Asia — to Afghan civilians subjected to Taliban governance, to Indian civilians targeted in ISI-backed attacks, to Pakistani civilians caught in jihadist blowback, and to the families of thousands of US, NATO, and Afghan forces killed by groups Pakistan simultaneously sheltered.
