Seriously though, the USA did not convert to a full wartime economy for the Iraq war; which it would surely have to do for a European war. I suppose we would also have to better define the parameters of invasion. If the objective is to conquer all of the EU then no, the USA can't do this. But I am sure the USA could successfully annexe part of the EU, i.e. conquer the weaker states like Portugal and Spain, and probably Italy at best.
The United States can't invade Italy or Spain, those two countries are way too impossible to invade. The best the United States could take is Portugal, and that is only if the rest of the European Union refuses to aid Portugal against the United States. And America would be gain immense losses fighting the Portuguese. Portugal is not Iraq.
Marina Militaria Italiana! The best navy!
Italia triumphs again!
“Italy unfortunately has been long excluded from the number of European powers. If Italians today are worthy of resuming their rights, someday they will see their country arise with glory among the powers of the earth.”--Napoleone Buonaparte
