“No President, Trump included, has the authority to take us to war without the consent of the people (House) and the States (Senate).”
Have you ever read about the Whiskey Rebellion? George Washington, who was close to the writing of the Constitution, sent troops to Pennsylvania to quell a public uprising. He did not seek authorization from Congress.
Likewise, Lincoln did not seek authorization from Congress in pursuing the war against the South.
So in your thinking, the President can wage war against the American people without authorization from Congress, but not enemies overseas.
The practical effect of this law is to give aid and comfort to Iran, an enemy who wants to destroy us. They, like you, rejoice in this law.
Washington's actions were authorized by the Calling Forth Act and the Insurrection Act.
Lincoln's war on the Southern states was completely unjustified.
So no, I do not believe the President can make war on Americans on his own, either.
Well, if Iran plans "to destroy us", they had better pack a lunch.
And if the representatives of the People and the States don't see it your way (and they don't) - there's another election in sixteen months, and you can try to convince the People that fighting more wars for other countries is a good idea, but I don't think the votes are there.
