The US did not retreat. We fought multiple wars to maintain our power and influence. We toppled multiple regimes to maintain puppet governments. Very much the same as the USSR and China have done.
Vietnam, Korea, Iran, Iraq, Cuba, Guatemala, Haiti, etc.
US conquest was quiet similar to British conquest. They didn't make their conquered people citizens (that'd make things tricky for exploitation) so instead they make sure the "democracies" they spread elected the right leaders who just so happen to align with US interests.
There's a reason the US has military bases across the globe. It's not because they've retreated from their subservient states.
