It's difficult to say what's more shocking: India's alleged involvement in a murder on foreign soil or how Trudeau has approached the issue. Canada has been caught off guard by a lack of vocal support from its allies, especially America, at a time when the global order desperately needs India on its side. Unfortunately for Canada, the dynamics of the new Cold War against China and Russia means that its issues with India aren't worth public confrontation.
The only way out of the spiraling decline in relations between India and Canada is for Trudeau's state to either prove or disprove its allegations and for India to cooperate with the subsequent investigations. Unless this occurs, ties between the two countries will continue to free fall – creating an incredibly difficult position for businesses, students, and tourism at a time when international unity is paramount.
There's a 70% chance that if WWIII occurs before 2060, the US and India will be on the same side, according to the Metaculus prediction community.
