Who would win in a war between America & the Galactic Empire?

dumb question but, Do you know why America is so powerful, becuase, if someone attacks or threatens us, we will waste no time in deploying thousands of soldiers AFTER we bombard and Nuke "dath vader" they would start planning Special Operations and black operations to take out any powerful militayr leader, Near the end, pull out all troops and continue to demolish it with nukes. and if it was on turf, it be harder, cuz about every American owns a gun of some sort.
