There is a way in which this whole situation has been revealing to me about how little some outside the US actually understand about US politics and civic structures, or alternatively have their own form of isolationism.

The heterogeneity in the US — culturally and in terms of political-legal structures — is far greater than those in Europe and Canada seem to understand sometimes. This is now combined with a corruption of democratic legal processes (e.g., gerrymandering) that make options outside of outright civil war a needle increasingly difficult to thread. There is a reason people are bringing up Hungary — it would be absurd to equate the EU with Hungary for the same reasons it's absurd to paint the entire US with a broad brush.

Something like 90% of people in the US opposed what was going on with Greenland. Just about the only people in favor of it in the US were the presidential administration and people trying to curry favor with it. What do you expect the other 90% to do? The legislators being petitioned were busy with a deluge of other immediate domestic problems — maybe people outside the US didn't understand the scope of the unaccountable fascist police occupation going on in cities such as Chicago, Minneapolis, or Los Angeles? Protesters in Minneapolis were being murdered by these thugs. That's not even getting into the dismantling of social safety nets, rampant corruption, Venezuela, etc etc etc

People outside the US do not want a US civil war. It's happened before and if it happened again would happen along the same geopolitical lines as before. It would be devastating not just to the US but to the rest of the world.

Treating everyone in the US as the same, without recognizing the very real divisions involved, or the structural stresses involved, doesn't help anything.

Everything happening in the US could happen everywhere. If you have enough politicians distorting and destroying traditional democratic mechanisms in favor of a criminal fascist and party domination, people have fewer and fewer options left outside of things that no one wants.

"The complete disinterest in international allies" is a dishonest statement, and I can only assume reflects total ignorance of what is happening in the US, and/or a self-serving defense mechanism to avoid really confronting the difficulty of what those in the US are faced with.
