"President Obama has decided to get tough with Russia by imposing sanctions and increasing support for Ukraine’s new government. This is a big mistake. This response is based on the same faulty logic that helped precipitate the crisis. Instead of resolving the dispute, it will lead to more trouble.
The White House view, widely shared by Beltway insiders, is that the United States bears no responsibility for causing the current crisis. In their eyes, it’s all President Vladimir V. Putin’s fault — and his motives are illegitimate. This is wrong. Washington played a key role in precipitating this dangerous situation, and Mr. Putin’s behavior is motivated by the same geopolitical considerations that influence all great powers, including the United States."
"When Mr. Putin explained why he was playing hardball, Mr. Obama responded that the Russian leader “seems to have a different set of lawyers making a different set of interpretations.” But the Russian leader is obviously not talking with lawyers; he sees this conflict in geopolitical, not legal terms.
Mr. Putin’s view is understandable. Because there is no world government to protect states from one another, major powers are acutely sensitive to threats — especially near their borders — and they sometimes act ruthlessly to address potential dangers. International law and human rights concerns take a back seat when vital security issues are at stake.
Mr. Obama would be advised to stop talking to lawyers and start thinking like a strategist. If he did, he would realize that punishing the Russians while trying to pull Ukraine into the West’s camp will only make matters worse."
