It's not exactly rosy as you say, but the leaders are increasingly open with Trump as to what they actually think (see Merz's latest comments) and he uses this as an excuse to realize what they planned a few years ago. There is zero chance that any Europen state starts bombing Iran.

OTOH, while refusing to do wrong is already something, there are limits to what they can actively start doing - and concrete consequences if they start doing something Trump doesn't like. He's highly unstable and can decide to take a decision that can be perceived as crazy, and harmful to the USA, but at the same time harmful to the ex-ally who decided to stand up to him. So the EU leaders basically do what they can to just wait the crazy guy out.
