The Minister of Foreign Affairs agrees to a meeting. Your envoy informs him that Oman will not back down, and is prepared to fight to protect its territory, with US and Iranian backing. However, your envoy also makes it clear that Oman much prefers a peaceful solution, and is prepared to let bygones be bygones if the UAE agrees to permanently forgo all claims to Musandam.
Faced with Oman's clear unwillingness to give up territory and the combined military might of Oman, Iran, and the US, the UAE backs down. A deal is struck, giving the UAE preferential access to Omani ports on the Strait in exchange for easier passage for Omanis traveling between Musandam and the rest of Oman. You succeeded in finding a peaceful solution, and perhaps the most efficient one as well. The Sultan is very pleased. Well done.
