The scenery changes, the fine print doesn't..... Defence pacts triggered automatically exactly once in history, in 1914, and they dragged the whole planet into a world war over one assassination........ Ever since, every pact is written with escape hatches precisely so that never happens again, which is why they are seldom acted upon.....
For recent examples if 1960s and 70s is too old for you:
Ask Ukraine about the Budapest Memorandum.....
Ask Armenia about CSTO in 2023
Ask Qatar which hosts the biggest US base in the region and still got bombed twice with zero response.....
This very pact exists because the American umbrella over the Gulf visibly failed.....
And your Sindoor point proves my argument, not yours...... India has no defence pact with anyone, nobody came, they fought alone, so did we, and we held our own..... That's literally my point, every nation fights its own wars. Thanks for the supporting example....
