This is Trump’s failure
Trump failed to inform allies of his intent to attack Iran and then, after things went south, they declined to help.
Trump failed to consult Congress before attacking Iran and, now that the Pentagon says they need $200 billion to pay for the cost and replenish their ammunition, Congress will be difficult to convince.
Trump failed to explain to the American people the goals of his war and, as midterms approach, we will see how completely voters throw the MAGA supporters of his incompetence out of office.
