A new poll shows most Americans think the Iran war wasn't worth it, and higher gas prices and a stretched military are fueling the discontent.

• Two-thirds of US adults say the Iran war has not been worthwhile, split sharply along party lines.
• Gas prices keep climbing since the fighting started, with the national average pushing higher.
• A US general warned the Pentagon it lacks enough Navy destroyers to defend both Israel and the US homeland from Iranian missiles.
• Trump is threatening another strike on Iran, even as munitions and warships run short.
• Much of the video contrasts the American cost-of-living grind with cheaper, less stressful life in Europe and China.

Outlook: Another possible strike on Iran looms this week, which could push gas prices and military strain even higher.
