A Foreign Policy analysis contrasts President Trump's handling of the six-month Iran war — costing at least $35 billion with no clear endpoint — with Franklin Roosevelt's deliberate campaign to build public support for World War II, including enlisting Donald Duck and other entertainers to sell taxes, bonds, and rationing to Americans. The piece notes the Trump administration's rationale for the conflict has shifted from eliminating Iran's nuclear program to keeping the Strait of Hormuz open, despite the strait having been open before the war started.
The analysis argues that presidents who fail to articulate a clear case for war risk losing public support once conditions on the ground worsen, and that the Iran war has compounded Americans' affordability concerns rather than easing them. Roosevelt, by contrast, used the Office of War Information and public messaging campaigns to justify sacrifice across the economy during WWII.
