Simple answer? There is not a single army or military in the world that stands a chance against the United States in active conflict that doesn't just nuke us. I'm not prideful or boasting but nobody has the tanks, anti mine armored vehicles, planes, aircraft carriers, or airplanes that we do. Hell Russia doesn't even really have tanks anymore. We could easily decimate them in a war without nukes. It would be all air superiority, drones, and naval bombardment. We would cut off their supplies to the Kremlin and flatten any cities that showed even slight troop buildup. It would be genocide.

China is a joke. Just because of the size of their men, and the laughably cheap gear they give them. It would be like fighting against women and children. Look up their new rifles, even in promo videos for these shit ass rifles they keyhole bullets (bullets shoot out of the barrel and tumble rather then fly with the point facing forward) meaning they couldn't pierce body armor due to their surface area upon impact.

Chinese military is a joke. Russian military is a joke. Americans are laughing.
