Air Strikes on Iran nuclear sites and some of their other military infrastructure does not require declaration of war or consent of Congress. In fact it is better to be done as big surprise of shock and awe.

The President can check the Congress that way, but he can't force it to do anything. Not declare war, not required in this case as you point out, and certainly not appropriate money. That's the thing the Congress holds over the President. They can cut off funding, without doing anything. The President cannot veto a funding bill that is never passed.
