What a crazy situation we are in! It looks like we'll get out of this reasonably fine, but there is still a risk that Ukraine will be pressured by the west into a peace deal where they don't get Crimea back. (Donetsk and Luhansk... I don't think they care much for those) If Ukraine doesn't get Crimea back, I don't understand why the Russia would not attack Ukraine again in a couple of years.
Trudeau probably won't affect Trump directly, but knowing about his call affects other western leaders. And the US populace as well.
