Fact is, the SAA must respond to this threat, immediately. If ISIS takes the city, it would be much harder to recapture it than to defend it. The question is, which troops can be redeployed. Weakening any front could promptly lead to another offensive. In the south, there could be a large scale offensive any time, anyway. The Islamist Hama offensive could be restarted. Damascus sent troops already to Aleppo, where tens of thousands of soldiers are deployed in and around the city, as well as in the surrounding area. In Latakia, the Islamists would be eager to launch an offensive.
