After ww2, the US was alone among the allies in not being broke, in fact they emerged financially stronger. They required repayment from the British almost immediately. Loans were which finally paid off in 2007. It took 62 years to repay. The requirement to repay the americans was part of the financial problems which meant it was years before rationing was ended in Britain, well into the 1950s.
The bankrupt nature of Britain and the US requirement for repayment mean the British were not just a threat to the US in post war years, but were forced to withdraw from their empire(not necessarily a bad thing), but effectively on terms dictated to by the US. For example when the British couldn't afford to assist Greece, the US stepped as part of the Truman doctrine.

What I'm saying is that the US used the war to destroy not just their enemies, but weaken their allies and make themselves dominant in the post war period. They extended their dominance from the Americas to the whole world.

Interesting, I've heard it the other way around: that the US wrote off a substantial part of the debts its allies had incurred during WW2, because it was obvious they could not be fully repaid. In any case, inflation during the decades after WW2 would have eaten up a huge part of the debts. And the US did organize the Marshall Aid Program, which helped rebuild Britain and Western Europe and never had any requirements of refunding.

You're right though that the war did mean the US established itself as a Superpower in the Old World, and that cooperation with Britain and France (de Gaulle's Free French Forces) wasn't always as smooth as it may look in retrospect. But the British Empire had never fully recovered from the First World War - it was bigger in 1930 than twenty years before and had better communications, but it was weaker, less cohesive, less sure of itself, less rich in terms of what the Empire brought to Britain (counting off what it cost to keep the whole thing going).
