The founders were particularly wary of giving the president power over war. They were haunted by Europe’s history of conflicts started by self-aggrandizing kings.

The founders would have been astonished by President Bush’s assertion that Congress should simply write him blank checks for war. They gave Congress the power of the purse so it would have leverage to force the president to execute their laws properly.

The framers expected Congress to keep the president on an especially short leash on military matters. The Constitution authorizes Congress to appropriate money for an army, but prohibits appropriations for longer than two years. Hamilton explained that the limitation prevented Congress from vesting “in the executive department permanent funds for the support of an army, if they were even incautious enough to be willing to repose in it so improper a confidence.”
