President Donald Trump blasted Pakistan for being a terrorist hotbed on Monday and stressed the need for stronger ties with India in remarks likely to worsen ties between the two nuclear-armed rivals.

During a speech focused on U.S. military engagement in Afghanistan, Trump accused Islamabad of harboring militants and warned of consequences if the government didn’t crack down on sweeping fundamentalism.

“The U.S. can no longer be silent about Pakistan’s safe havens for terrorist organizations, the Taliban and others, that pose a threat to the region and beyond … No partnership can survive a country’s harboring of militants,” he said.

A few sentences later, the leader brought India into the equation.

“The U.S. will further develop its strategic partnership with India,” Trump said, referring to the realm of counter-terrorism. Washington wants New Delhi to help more with Afghanistan in areas of economic assistance and development, he added.

While previous U.S. administrations have long echoed similar views, siding with India immediately after criticizing Pakistan is a risky gambit, according to strategists.

Trump’s comments are polarizing a deeply divided region, said Jan Zalewski, a senior South Asia analyst at Verisk Maplecroft. Islamabad views New Delhi as a key national security threat, so the U.S. praising India while chiding Pakistan isn’t likely to go down well, he explained.

In fact, Trump’s remarks could even increase terrorist activities.

“Many terrorist groups in Pakistan maintain an overtly anti-Indian agenda, [so] a significantly increased Indian role in Afghanistan would likely increase terrorism risks against Indian targets in Afghanistan and in India itself,” warned Zalewski.

Both South Asian giants, who are historical arch-enemies, face numerous threats from international and regional terror groups, including the Islamic State, Al-Qaida in the Indian Subcontinent, Lashkar e-Tayyiba and Jaish-e-Mohammad.

Pakistan witnessed 734 terrorist attacks in 2016, according to recent figures by the U.S. State Department, compared to India’s 927 incidents and Afghanistan’s 1,340 figure.

The president’s speech also doesn’t bode well for regional anti-terror operations.

“The fact that Trump is taking sides could hurt counterterror initiatives between India and Pakistan,” said Rohan Gunaratna, head of the International Center for Political Violence and Terrorism Research at Singapore’s Nanyang Technological University.

“He shouldn’t be playing favorites. The ideal U.S. strategy should be uniting India and Pakistan because both these countries are victims of regional terror groups,” he added.

In the past, New Delhi and Islamabad have attempted to strengthen joint counterterrorism operations, but territorial clashes, particularly concerning the disputed region of Kashmir, emerge as regular obstacles.

“The approach Trump is taking reflects a deep lack of knowledge and is short-term nature, it won’t help improve the status-quo,” Gunaratna said.

Domestic groups executing attacks against Pakistan’s civilian and government targets include the Tehrik-e Taliban Pakistan, the Afghan Taliban and its affiliated Haqqani Network. India’s homegrown threats, meanwhile, range from armed Christian separatists in Assam to Maoist rebels.
