Iran wanted the Lebanon war to end before talks, to take credit for ending it, and the US wanted Hormuz to be opened, so that negotiations would be focused immediately on the nuclear issue.
The involvement of Iran (ancient Persia) in Lebanon war and regional tensions connects to Ezekiel 38's prophecy where Persia is explicitly named as part of the Gog coalition. The Hebrew term פָּרַס (Paras) directly identifies Iran as a key player in end-times Middle Eastern conflicts involving Israel's neighbors.
Regional warfare in Lebanon and tensions over the Strait of Hormuz reflect the broader pattern of 'wars and rumors of wars' and 'nation rising against nation' that characterizes end-times conflicts. The ongoing Middle Eastern tensions fit the general framework of increasing international conflict before the end.
While not the Euphrates specifically, the Strait of Hormuz represents a critical waterway whose closure/opening affects global commerce and military movements. The geopolitical significance of controlling key water passages echoes the prophetic pattern of waterways being strategically important in end-times scenarios.
