Iraq to Syria to Jordan hitchhiking?

Hello! A friend and I are planning to travel through parts of the Middle East and North Africa this summer. We had originally planned/booked a flight from Turkey directly into Amman but it was recently cancelled and we are trying to come up with other options. Our backup is just to purchase another flight but it would be wonderful if there was an alternative way. Has anyone had any luck/experience hitchhiking in this area?

We are considering either flying into Baghdad and then trying to hitchhike to Damascus and then Amman. I speak a little Arabic (at least enough to make some basic conversation and get around) so I’m not too worried about that, but I’m unsure if hitchhiking is a feasible plan. Are there buses that take this route? Should I bring things to barter with? Would a guide be recommended? Any advice would be appreciated!
