I don't believe Egypt or UAE will be willing to take part in a coalition in Syria. We won't get international support if we do, but I advocate intervention there. The groups on the ground unlike in Yemen are able to advance under cover of air strikes. But in Yemen I don't understand what caused decision to end operation? Because Houthis will not disarm and now Iran wants to 'help' form new government which means interfere and make it mostly Shia government. Abdel Malik Al Houthi is also making victory speech tonight. This isn't an agreement, more aggression will come in future as long as twelver idiot runs movement.
No ends of military operation rather the second phase of it just started. Fighter jets are conducting sorties around Sana'a as we speak.
I have read reports that Houthis accepted UN resolution and also that Egypt is forming the base structure of new Yemeni army. Also Houthis are calling for dialogue. They expect to have a disproportionate representation in new government but they won't get it. So it seems Saudi is playing it well, this looks like Houthi surrender but nevertheless Iranians will mock Saudi Arabia and claim it accepted defeat.
