Analyse på Foreign Affairs.com, amerikansk udenrigspolitisk tænketank : But this account is wrong: the United States and its European allies share most of the responsibility for the crisis. The taproot of the trouble is NATO enlargement, the central element of a larger strategy to move Ukraine out of Russia’s orbit and integrate it into the West. At the same time, the EU’s expansion eastward and the West’s backing of the pro-democracy movement in Ukraine — beginning with the Orange Revolution in 2004 — were critical elements, too. Since the mid-1990s, Russian leaders have adamantly opposed NATO enlargement, and in recent years, they have made it clear that they would not stand by while their strategically important neighbor turned into a Western bastion. For Putin, the illegal overthrow of Ukraine’s democratically elected and pro-Russian president — which he rightly labeled a “coup” — was the final straw. He responded by taking Crimea, a peninsula he feared would host a NATO naval base, and working to destabilize Ukraine until it abandoned its efforts to join the West.
