I think they might honestly be going for fulfilling greater “israel” and trying to cut off Hezbollah and also use these forces perhaps to attack them from another side, grind them down and just basically win. Then they can finish the genocide whenever they want while Iran is isolated in their own little corner, cut off from the belt and road, cut off from BRICS, unable to wield influence and at that point you have an isolated and besieged Iran and an isolated, starved and besieged Yemen both separated by multiple countries and distance and unable to help each other meaningfully. Of course Iraq complicates things a little but I suppose they might plan to do something there eventually and even with a theoretical Iraq in Iran’s corner and a theoretical situation where the US actually finally leaves (seems even less likely now) the situation, the chessboard is bad for BRICS, Iran, and multi-polarity. Much worse than it was before October 7th 23 and it was pretty bad then with all those Arab states cozying up to the zionist occupation through US brokering. At least then they still had an intact Hezbollah with leadership, supply routes, Assad, etc.

Just shows how quickly the board can change versus a determined, experienced opponent like the US.
