Over the past year, I’ve found John J. Mearsheimer my favorite foreign policy expert. He writes:
…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.
Putin’s pushback should have come as no surprise. After all, the West had been moving into Russia’s backyard and threatening its core strategic interests, a point Putin made emphatically and repeatedly. Elites in the United States and Europe have been blindsided by events only because they subscribe to a flawed view of international politics. They tend to believe that the logic of realism holds little relevance in the twenty-first century and that Europe can be kept whole and free on the basis of such liberal principles as the rule of law, economic interdependence, and democracy.
