Obama learned this the hard way, when he drew a “red line” against Syria’s use of chemical weapons and then failed to act forcefully when Syria crossed that line. The Obama doctrine cannot be credible if the US is not willing to use the capabilities that the president has pledged to preserve.
奥巴马就有此沉痛教训。他给叙利亚使用化学武器的行为画了一条“红线”，而当叙利亚越线时，他却没有果断行动。如果美国不愿使用其总统信誓旦旦要保留的实力，奥巴马主义也就不再可信了。
