Very little to do with each other. Rome was trying to take over the world and killed at will, torturing and for sport. The US has always tried to help other countries from tyranny, even if they made mistakes along the way. They both had slaves for labor and to use, at least some in the US south. Slavery of course is higher now than ever before, with a lot of it here in Thailand. Rome and England was closer in actions, Rome not racial as far as slavery but England was. Rome was genocidal in action while taking over territories. The US isn't trying to take over territories by force or killing. It's trying to install democracy into a few places so the people are free from protest killings, rape and torture. America says wars are for defense or protecting freedom while Rome wanted total control. Rome had games where people were slaughtered, for entertainment. Britain tried taking over Africa, Tasmania and Asia, killing thousands, the same as Rome did in it's European expansion. Much the same on control but for different reasons, unlike America's goals. Of course some will argue it's still mostly about oil but the main reasons are eliminating a dictatorship where killing is for control. Some think America uses machiavellian actions but are still wanting Iran to have that democracy with better leaders and not for their own control.
