The US used up a big chunk of its advanced missile interceptors defending Israel from Iran, leaving both countries low on supplies and badly exposed if fighting restarts.

• A Pentagon assessment shows the US fired more interceptors protecting Israel than Israel did itself, while Israel is down to double-digit ballistic missile interceptors.
• Iran can make ballistic missiles faster than the US can replace the interceptors, and the US fires 10 or more interceptors at each incoming missile.
• Trump has no good military options left and seems to be stalling, hoping Iran's government collapses on its own; restarting the war would hurt his poll numbers and push gas prices up before the midterms.
• The same shortages would leave the US badly exposed if China moved on Taiwan, which would cut off chip supply and hammer the economy.
• Trump joked he could run for prime minister of Israel since his approval there is far higher than at home, and said he might skip his son's wedding because of the Iran situation.

Outlook: New fighting could restart within days, and another round would drain US and Israeli missile defenses even faster with no quick way to refill them.
