I've just left this comment at my Congressperson's "contact" form on her website:
"Do NOT under any circumstances, allow the Lunatic-in-chief to get America bogged down in yet another unwinnable, immoral, unconstitutional war or "police action" or whatever he wants to call it; We MUST stop wasting American lives and treasure intervening in other countries' civil wars. It would serve ABSOLUTELY NO PURPOSE, and would FURTHER UNDERMINE America's credibility around the world."
Find out who your representative is and send this or a similar message - call, fax, email, or even snail mail.
Freedom is my Worship Word!
