With tensions rising in India and Pakistan, it was only a matter of time before Trump had to step in and put his foot in his mouth. Basically, what happened is the Trump administration announced a ceasefire and peace talks between India and Pakistan…seemingly without consulting either side.
The tit-for-tat military exchanges between India and Pakistan were bound to end in peace talks anyways, but having a third-party (i.e., the US) step in, goes against everything in the “how to engage with India” handbook. And given the extreme disparity between India and Pakistan’s demographic and economic situations, external mediation undermines the Indian position. So, feelings were hurt.
And when feelings get hurt, relations and policies will suffer. That means US-India relations are at their lowest point in decades, and all those years of developing a closer relationship with India went up in smoke.
