How about a European alliance that, for the most part, pays its own way and clearly identifies the enemy that has already conducted an invasion of almost every nook and cranny of Europe except for Hungary and Austria. After clearly identifying that enemy, how about developing and implementing a plan of action (with the necessary military force) capable achieving victory over (i.e. destroying) that enemy not just on home soil but back to the source.
That would be a European alliance, not a U.S.-European alliance. So drop the whole farce of NATO and let Europe stew on their own. If they create their own alliance to replace it then that’s their decision.
