It doesn’t go nuclear.

Pakistan's top nuclear scientist sees "very dim" chances of a nuclear war with neighboring India despite mounting tensions between the two arch-rivals in recent months.

"I won't say a zero chance but there are very dim chances of a war between the two neighbors involving nuclear arsenal despite escalating tensions," Samar Mubarakmand, a former chairman of Pakistan Atomic Energy Commission (PAEC), and head of a team of the scientists that conducted six "successful" nuclear tests in remote Chaghi district of southwestern Balochistan province on May 28, 1998.

Islamabad's move had come only two weeks after New Delhi conducted five nuclear tests during a period of May 11-13,1998 in Pokhran range of Rajasthan state, which borders Pakistan's southern Sindh province, triggering a new arms race in the already tense region.

"Pakistan had no other choice but to pay India back in the same coin after its nuclear tests to maintain strategic balance in the region," Mubarakmand said.

The two hostile neighbors have already fought three full-fledged wars – in 1948, 1965, and 1971 – and a three-week long Kargil skirmish in 1999.

Already heightened tensions between the two countries plummeted to a new low after New Delhi scrapped the longstanding special status of disputed Jammu and Kashmir region last August following an air combat between the two air forces in February 2019.

Since then, the two border forces have been engaged in almost daily clashes at the Line of Control (LoC), a de factor border that splits the scenic Kashmir valley between the two rivals. Apart from Kashmir, the two countries have been locked in a string of sea-and-land disputes, amid several "successful" missile tests.

"The leadership of both countries are fully aware of the catastrophe a nuclear war can cause. They won't go for that option no matter how tense the situation is," observed Mubarakmand, who served at PAEC from 1962 to 2007 and played a key role in developing the country's nuclear program.

Conventional provocations, he said, would continue between the two longtime rivals but, he reckoned, both sides would not "cross the limit" to go for nuclear option.

"Both countries have long been reeling from poverty, illiteracy, and other health and economic issues. Wars or undue competition in arms race are not in the interest of the two nations," he maintained.
