I am talking about actively hindering the war effort while getting closer to Iran, a country that repeatedly kidnapped europeans, or caving in for China again and again.

Europe has always managed to make the wrong choice historically, and that's how it still continues

How has Europe actively hindered the war effort? Not volunteering for demining duties under fire in a very narrow straight, and preferring diplomatic solutions seems eminently sensible, and not at all the same as 'getting closer to Iran'. Why doesn't the US send frigates and destroyers into the straight to open it and escort ships out? The answer is that it's pretty high risk, and not one worth taking (unless you are Trump and looking to save face).
