The thing is the EU is mostly concerned about Europe, while the US wants to play world police. So if China would invade Taiwan and NATO is without the US, I’m not sure they are going to get involved, it would open the gate for Russia. If the US is still part of NATO I’m not sure what will happen as it’s not an article 5 event. So the other NATO countries are not automatically involved even if the US is.
