India and Pakistan

The history between India and Pakistan, both nuclear powers, is inextricably linked. The countries have fought a series of wars since gaining their independence from Great Britain in 1947, largely over the Kashmir region, to which both countries lay claim.

India became a nuclear power in 1974, and Pakistan became a nuclear power in 1998.

Neither country has used nuclear weapons in conflict, but many experts fear that the ongoing crisis could escalate beyond conventional weapons use.

India has approximately 164 nuclear warheads, and has land-based, sea-based and air-launch nuclear capabilities. The state had declared a No First Use policy, which means they have vowed to never use nuclear weapons first in a conflict. However, as of August 2019, India said they are reconsidering this policy.

As of 2024, Pakistan has approximately 170 warheads and continues to gradually expand and modernize their nuclear arsenal. This number exceeds the projection made by the U.S. Defense Intelligence Agency in 1999 that Pakistan would have 60-80 warheads by 2020. There is little public information on Pakistan’s nuclear arsenal as the Pakistani government has never publicly disclosed the size of its nuclear arsenal, making it more difficult for experts to estimate the arsenal’s size and composition compared to other nuclear-armed countries. Pakistan keeps its nuclear warheads stored separately from its missiles and will only assemble one if it will be used. Unlike India, Pakistan has not declared a No First Use policy, and instead has opted to emphasize smaller battlefield or “tactical” nuclear weapons as a counter to India’s larger and superior conventional forces.

Even a small nuclear exchange between India and Pakistan could kill 20 million people in a week. If a nuclear winter is triggered, nearly 2 billion people in the developing world would be at risk from death by starvation.
