- Syria has been the main conduit for Iran to ship weapons to their Hezbollah client in Lebanon. If the Syrian regime falls, it will be much more logistically challenging for Iranian weapons to reach Hezbollah;
- Syria, Iran and Hezbollah have formed an "axis of resistance" against Israel and more moderate Arab regimes;
- Finally, the sectarian connection is natural. Hezbollah is Shiite, and Alawites are an offshoot of the Shia branch of Islam as well.
