Granted that the Reds in France and Germany are not to be relied upon. BUT, if you hadn't noticed, some of those Euroweenies are still considered valuable allies...remember Great Britain? And especially don't forget how much heavy U.S. national security mech...and personnel, happens to be located in these countries. Not to mention our bases in bases in the Middle East (such as Kuwait, UAE, Iraq, etc), or the Indian Ocean at Diego Garcia, or maybe even the Far Pacific, such as Guam...
Based on your cavalier dismissal, you must not care about them either.
Lets do it your way. Lets go in and bomb the crap out of Iran and then let those same Euro-weenies you are so worried about tell us how terrible we are for saving their ass.
