If you take into consideration the states once behind the Iron Curtain, then I suppose the Russians were pretty up there with America, though only during the Cold War. Today's Russia, however, is decidedly on the rebound.
If you consider Western Europe (particularly Italy and West Germany), the Middle East, Central and South America, South Asia and the Pacific states during this period and continuing after, then I think as far as the forces of globalization go and the state interference that has more profoundly shaped the world of today, then I'd wager to state that the US comes out on top, and not by an indifferent margin. I mean it comes with the winner's (not loser's) territory, doesn't it?
Britain and Israel have worked in close ties with the US throughout the period and, as far as Britain specifically goes, one should also consider the history of the colonies till the 1960's. Whereas Israel has played an active role with its Knesset in penetrating into the affairs of the Arab world from the Maghreb to the Caspian see since its foundation.
On the China account, I think we're only at the beginning. On tomorrow's stage, however, they will probably take back time on Britain and Israel and during the
third week should be giving America a run for the money.
Of course this is how I interpret the race.
PS. Your Polish background, with respect to Russia, has no doubt colored your interpretation of the same race.
