Well moving EU troops into Ukraine would rapidly cause Russia to go to war with the EU, and in short order, US would be forced to make a decision as part of NATO.
Unfortunately I suspect the US would use the moment to backstab the EU, abandon them, and attack Canada, Greenland and Mexico, since no one could come to their defense.
We need an alliance with China.
Did you read the US national security policy they just released? Have you been listening to everyone over the last few days? They make it very clear they intend to secure the Western hemisphere because they think it belongs to them. Your country thinks my country belongs to you. Trump is very likely going to move on Greenland, and once the pretense is gone I imagine he would do exactly what he claims to want to do, in formal policies and all over the media.
I don’t know why Americans seem to think “oh he’s just joking this time”. A rule of thumb: If it involves making people’s lives worse, he’s not joking. He wants to control the Western hemisphere and if he has to kill millions to do it, he will.
You’re in denial if you don’t think Trump is going to drive the world to war. Or maybe you happen to believe that my country does in fact belong to the US?
