How will they get to Syria? Iran has no common border with Syria. They will either have to:
1. Drive through Northern Iraq (Iraq wouldn’t allow it)
2. Fly over Iraq (I doubt/hope Iraq wouldn’t allow that)
3. Sail through the Suez Canal (Egypt may not allow it and if they did Israel would be able to take the out as they will be bottle necked)
Why not send them through Russia?
2. Fly over Iraq (I doubt/hope Iraq wouldn’t allow that)
They’ve been flying arms across Iraq for a while now. I imagine this is the likely method of deployment Iran will use.
