Your comment regarding Trump is a strawman and has nothing to do with this issue. The fact is he was the one who told Germany not to do the Nord Stream 2 pipeline, that it would weaken them in dealing with the Russians. . So here we are, barely months from Biden approving it that it's become the issue we warned about. The question is, if Europeans aren't interested in stopping Russia, why should we take the lead? It's their backyard. Let them live with decision and their pipeline and work it out themselves. Apparently, Germany cares more about gas than they do about Ukrainians.
Canada is going to get dragged into this as a NATO country. Do you want to risk Canadian lives battling Russian tanks when the key European countries could care less?
First, your statement that "European countries could care less" is simple-minded nonsense. Nobody, especially Canada is going to go to war against Russia if the Europeans don't themselves. Honestly, how do you dream this "bar talk" up?
And I don't understand what you mean by Biden approving the pipeline? What does the US have to do with what Europe negotiates with Russia?
But there's another aspect here. As bad as we think/know Russia is, the fact that some countries still want to deal with them, to your displeasure, might mean that they might not view the USA as benign a friend as much as they used to. Don't you think that Trump had something to do with that change? If I may say so, you seem to argue from the point of view that everything that goes on in the world should be to the benefit of the US and anything that isn't is bad by definition. Even you should realize that US foreign involvement has not always been benign or beneficial to other participants. At this point, you're probably going to bring up WW2 again, but that was close to a century ago now and a lot has happened since then.
Maybe some countries don't trust the US as much as you think they should? Why would that be.
