Given the wall-to-wall coverage of the US and its war on Iran, it looks very much like Trump is the key player. He is not. The United States may have far more military power than Israel, but the key player is Benjamin Netanyahu.
Moreover, the Israeli prime minister has fallen into a trap of his own making, and is dragging Trump and the US military into that same trap. For Israel, and indirectly for the US, the war has to end in total victory. Anything less is pointless.
