When–and why–did India and Pakistan become bitter rivals? The Indian subcontinent is home to some 1.5 billion people who share deep cultural, linguistic and historical ties, but for nearly eight decades, the Indian-Pakistan relationship has been marked by tension, violence, and sometimes all-out war. On Ian Explains, Ian Bremmer breaks down the complicated history of the India-Pakistan conflict to understand why tensions are once again rising after a military clash between the two countries in May 2025.

There are many complex reasons that India and Pakistan have become such bitter rivals. Bremmer unpacks four key issues: the partition after nearly two-centuries of British colonial rule, contested claims over the Kashmir region, the development of nuclear weapons, and leaders stoking nationalist and religious tensions for political gain. A terrorist attack in Kashmir last spring led to an exchange of military strikes and showed the world just how dangerous escalation between two nuclear powers can be. Watch Ian Explains to understand the roots of the conflict and why decades of tensions and war probably won’t be resolved any time soon.

For years, Russia has counted on one advantage above all else: time. Ian Bremmer explains why Ukraine's expanding campaign inside Russia is challenging that assumption, and what it could mean for the future of the war.

The US president used a primetime address last night to argue America’s election system is broken and vulnerable to “rigging.” He pointed to documents he says show Chinese interference in the 2020 vote. But the evidence Trump offered, along with past assessments from the intelligence community, doesn’t support his broadest claims.
