The United States had 500,00 military deaths, Great Britain had 326,000 Military Deaths.
After we bailed Europe out, we rebuilt them:
As the war-torn nations of Europe faced famine and economic crisis in the wake of World War II, the United States proposed to rebuild the continent in the interest of political stability and a healthy world economy. On June 5, 1947, in a commencement address at Harvard University, Secretary of State George C. Marshall first called for American assistance in restoring the economic infrastructure of Europe. Western Europe responded favorably, and the Truman administration proposed legislation. The resulting Economic Cooperation Act of 1948 restored European agricultural and industrial productivity. Credited with preventing famine and political chaos, the plan later earned General Marshall a Nobel Peace Prize
You're wasting keystrokes. The British narrative is that we got into the war late, as if it were some kind of mutually-agreed upon game to which we had been tardy. In truth, we fought Germany mainly because of sentimental ties to Britain (in spite of equally strong sentimental ties to Ireland, Italy and Germany), but the average Brit seems to think we were late to the game, as if it were any of our business, in the first place.
