Explain this in more details. The outline I gather of your position is that "the US killed Ben Laden on Pakistani territory so India killed someone on Canadian territory, Canada had it coming for what they did to Ben Laden". Fill in the details.
If you harbour terrorists who are wanted by your ostensible partners, don't be surprised if they lose patience and decide to take matters into their own hands.
I don't care how you were raised, but two wrongs don't make a right, and unilateral, extrajudicial, extraterritorial assassinations of political opponents are wrong, even if you shout "terrorist!" while murdering
imagine if such shouting made murder okay, like a secret, magical incantation any arbitrary thug could recite to immunize oneself from guilt - it's a ridiculous concept when you think about it!
