The most consequential statement by former Secretary of State Hillary Clinton in Wednesday night's debate was her pronouncement that a no-fly zone over Syria could "save lives and hasten the end of the conflict," that a no-fly zone would provide "safe zones on the ground" was in "the best interests of the people on the ground in Syria" and would "help us with our fight against ISIS."

It would do none of the above. A U.S. attempt to impose a no-fly zone in Syria would, as Secretary Clinton once cautioned a Goldman Sachs audience, "kill a lot of Syrians," and, according to the Chairman of the Joint Chiefs, General Dunford, lead to a war with Russia. If the U.S. has not been invited into a country to establish a "no-fly zone" such an action is, in fact, an invasion, an act of war.
