Mr. President, here's why Assad has to go

If the war isn’t halted, millions more civilians will remain in jeopardy. Daraa, where the Syrian revolution began in 2011, is now apparently the next target in the regime’s sights. Then there’s Idlib, a northern province swollen to a population of more than 2 million, increasing daily by residents forced out of Eastern Ghouta. Civilians in Idlib are targets almost daily of regime and Russian bombing.

There’s also the possibility that Syria will ignite a regional war. Iran’s stated goal of forging a land corridor to facilitate the delivery of arms to Hezbollah in Lebanon, coupled with plans to settle large numbers of Iranians linked with the IRGC in Syria, already is seen by Israel as a severe threat.

The horizon is bleak.
