The net result of this is most likely to increase the stature of India. Now that Trudeau has accused India, if he cannot put India on the mat it will look like a loser. I do not think Canada has in it to pull this off. The world is way too connected and the US, the UK, and Australia will not like to take it to the extent where they damage their relationship with India. Eventually, they have to work to find something which gives an exit route to Trudeau.
Eventually, it will go nowhere, and since Canada will not be able to put any Cost on India. India's stature will grow.
One should not allege anything, if one is not sure to take it to a conclusion.
Trudeau shows how electing immature leaders like Rahul Gandhi can bring their country down.
