Could Our Country Win WWII Now?

I'm pretty sure we couldn't and it's a good thing we don't have a true rival for power at the moment. One of the liberal foreign policy comments I hate the most is that we empowered Osama Bin Laden in Afghanistan, implying that we caused all this harm on ourselves. This is of course, total foolishness in that we also helped modernize Japan both economically and militarily during the Meiji Restoration....and they still attacked us at Pearl Harbor. Should we not have responded? What the logic assumes is moral perfection - a perfection that never has and never will exist. It is utopian at best, purposeful half-truth at worst.
