Sure. In terms of the United States' policy on Ukraine, I would say traditionally the American position has been to support Ukraine through NATO, through the EU, and directly. There are definitely strong allies in Congress and in the Senate, who have visited Ukraine and who understand the situation in the contemporary setting.
We haven't seen Russia change tack through any of the interventions that have taken place thus far. Certainly the Canadian military mission is one of many training missions by other militaries from the NATO countries that are training troops in Ukraine as well: Poland, Latvia, the Americans, and the Germans. None of it has yet been enough to convince Russia to change course. The current U.S. administration and its views on this topic are under close scrutiny, both in Ukraine and Canada, as they are everywhere in the world. We don't really know what to speculate will happen next.
