On August 3, 2012, the fifteenth day of the government offensive, rebels in the city said they were desperately low on ammunition and expressed dismay that the international community had not reacted when a huge massacre could be coming. Again, Libya was the example. Gadhafi threatened to overrun Benghazi and when he tried to do it, NATO started bombing. Now in Syria, Assad was threatening to crush the opposition in Aleppo and had already started doing it, but Washington’s reaction was only hand-wringing. In my conversations with rebels it was clear they were becoming increasingly disheartened and desperate. (The rebels would usually communicate with each other on Skype, blending in with the billions of people using the Internet instead of going through cell-phone towers.) The United States was apparently still skittish about sending in arms because it feared they would end up in the hands of Islamic extremists, but that, like so many unintended consequences of US foreign policy in the Middle East, was a self-fulfilling prophecy. At this stage the rebels were numerous, strong, motivated, and moderate and I made that clear in my reports on the air.
