"What kind of Syria might follow the fall of the Assad regime? For many years, a significant percentage of American and Israeli military officers thought things would get worse. A new regime would be dominated by the Muslim Brotherhood, many said—including some of the highest-ranking American generals.
I have always thought this was a foolish position, given what Assad’s Syria was actually doing. How much worse could things get than a regime that was Iran’s only Arab ally, gave Iran a port on the Mediterranean and a border with Israel (through Hezbollah in Lebanon), helped Iran arm Hezbollah to the teeth, built a nuclear reactor with North Korean help, brought jihadis to Iraq to kill American soldiers, and viciously repressed the Syrian people. Moreover, the notion that the Muslim Brotherhood would rule after Assad was just that, a notion, never supported with hard evidence about their level of internal support."
