Then what purpose does it serve to write an amendment telling the President he cannot start a war with Iran if the President already understands that fact?
Good question, seeing as he can legally pound them for 90 days before justifying it to Congress.
That said, how many wars have we had since the last time Congress declared war? Hmm?
He can only legally attack Iran in a national emergency precipitated by them attacking us.
And the second question speaks directly to the reason I said that Congress is trying to regain its Constitutional authority.
They already have. Trump's restraint was remarkable.
As someone said, Congress never lost it.
That was not a national emergency, clearly.
Oh, and the President has 48 hours to justify his actions, not 90 days.
