Trump was wrong to involve America in Israel's hatred for Iran in the first place. He's currently stuck between a rock and a hard place.
He just admitted a few days ago that America's reserves are almost depleted and that if his war continues, there will be "bedlam" here at home. But he can't honor his MOU with Iran as long as the actual President of the USA, Netanyahu, continues to bomb apartment buildings in Lebanon.
Trump's only hope is to warn Israel that all financial and military support will be halted unless they cease hostilities. But Trump is a hardcore Zionist so that will NEVER happen.
