Broadly speaking, the governments and people which most closely identified with the United States have lost out. In the Middle East, Saudi Arabia, Jordan, the Gulf States, Turkey and Israel are feeling sore. Regimes, like Mubaraks Egypt, which had put all their eggs in the American basket, then found them addled. Many fell. In the Far East, old US allies feel inadequately protected from the rising power of China, and in Africa that same rising power has been left free to buy the place up. The great Obama pivot to Asia seems to have pivoted away again. Even western Europe feels neglected.
As for Britain, the bust of Winston Churchill left the Oval Office as Mr Obama moved in, and we lost influence. Just now, we have been embarrassed by US security failures in the Edward Snowden affair, and it seems quite likely that US changes proposed as a result of it will amputate some of the intimate intelligence cooperation that has helped us so much since 1946.
So the rewards for doing the right thing by the United States seem to have diminished sharply. I am not saying that all the countries just listed are notable practitioners of Ubuntu. Saudi Arabias very name referring as it does to one family is a denial of the oneness of humanity. But the list looks pretty good compared with that of the anti-American countries on which Obamas America is now smiling.
