WASHINGTON — An administration that lacks a consistent foreign policy philosophy has nevertheless established a predictable foreign policy pattern. A popular revolt takes place in country X. President Obama is caught by surprise and says little. A few days later an administration spokesman weakly calls for “reform.” A few more days of mounting protests and violence follow. Then, after an internal debate that spills out into the media, the president decides he must do something. But hoping to keep expectations low, his actions are limited in scope. By this point, a strategic opportunity is missed and the protesters in country X feel betrayed.
