USA is no longer wanting to appear reasonable. It has forever said goodbye to being the world police with limited liability.
Instead it's now only after its own simple selfish gains. And it won't face other predators but instead work with them if deemed worth it.
The biggest threat to Europe is no longer Russia or china. The most immediate threat to European soil is by the us in Greenland.
I don't think that trump and Vance are going to stop short of what they announced. They will go for Greenland.
This time the roles are reversed. It's no longer the US saving Europe as in the World wars.
This time it might go all the way around that the US also invade Canada and that Europa has to find it's position to bringing them to their senses.
At the end of the day this means that borders become increasingly uncertain.
The question is what policy will prevail. Predator logic or community based on the protection of minority rights.
Btw. I favor the later but I'm also not a fan of the strict division of nations by borders.
Actually I do what I like. I just never want to go back to a regular employment.
