Syria

first video is out of date. Iran-backed militia & Hezbollah are not in the South any more. Hezbollah are pretty much back in Lebanon & the Shiite militiamen have gone East. It was a deal worked out beween Israel & Russia where Israel doesn't do airstrikes in the South if Iran's influence is out of the region.

Without the Israelis defending them the terries in the south fell within weeks.

The rest of the video is stupid, framing it as a proxy war between Iran & Saudi Arabia is just BBC propaganda. Iran wasn't involved for years while the Brits were secretly doing their thing to helping to try to topple Assad. Britain still sells a lot of weapons to the Saudis. Remember that next time you hear them pipe up @ the UN about democracy or human rights.
