An I-400 raid on Washington would be strategically disastrous

Seiran aircraft might reach Washington in December 1941, but burning symbolic targets would intensify American resolve without giving Japan useful strategic leverage.

Question

Could I-400 aircraft bomb Washington on 7 December 1941, and would it help Japan?

Short answer

They might reach and damage symbolic targets, but the raid would be a strategic blunder that strengthened American determination.

Notes

The United States was unusually open to surprise attack before wartime defenses were established. Three submarine-launched aircraft could cause fires and symbolic damage around the White House or Capitol. That tactical success would not reduce American war-making capacity. Instead, attacking national monuments on the same day as Pearl Harbor would deepen public anger against a Japan unable to compel the United States to surrender.
