Regarding the war, I can assure you that Trump not excluding to take Greenland my force has been seen by the EU as threat of starting a war, giving that Greenland is part of the EU. Also applying tariffs when European NATO countries sent some troops in Greenland has been perceived as: "Trump wanted to invade Greenland, he felt like EU countries wanted to defend it, so he imposed tariffs because he wanted to invade".
I'm not saying everyone in EU is thinking this, but I think a lot of people did, and this is some context for you to try and understand europe's point of view.
