What do you think will happen to your country if it is not the next dominating power? The nature of strategy makes it certain that we will always live in a brutal world so long as brutality is a by-product of effective coercion. The best we can hope for is to live under the protection of tyrants.
EDIT: I would also note that we in fact gained over Ukraine. It was Russia's historically; in fact, we faithfully swore to Gorbachev in the days of Clinton that NATO would never go east of Germany. Instead, after we perceived the weakness of Russia, we advanced NATO up to Russia's very borders. Today, it makes news headlines when Russia dares to mass troops on its own border; what kind of power or rivalry is this? U.S. is trying hard to encircle Russia.
