The United States itself is a spin-off of the British Empire. I'd say that counts for something.
Well I disagree on multiple fronts and here is why:
1. The US is a continental size nation while the British were a island nation and that gave us for example access to far more resources than the British had which is why the US is no where near reliant on colonies as the British were as well. To get a perspective how big the US is, the distance from Lisbon to Moscow is still over 250 miles shorter than the distance from San Francisco to Boston.
2. The US has far more hard military and economic power than the British ever did. The Royal Navy while comparable to ours, their ability to fight a war on land was no where near as extensive as ours. It is why they tended to always try to maintain the existing balance of power which is very different than the Foreign Policy of ours since 1945 with the possible exception of detente.
3. The US morally has not done anywhere near the bad stuff the British did
