We'll leave aside the question whether any authorization for operations of the U.S. military in Iraq is still valid after all these years. Be that as it may, Reps. Gabbard and Scott deserve our thanks for putting their finger on the precise problem respecting Obama's covert war on the sovereign nation of Syria – its unconstitutionality:
“Reps. Tulsi Gabbard, a Democrat, and Austin Scott, a Republican, introduced legislation on Friday to end what they called an “illegal war” to overthrow Assad, the leader of Syria accused of killing tens of thousands of Syrian citizens in a more than four-year-old civil war entangled in a battle against IS extremists, also known as ISIS.
“The U.S. is waging two wars in Syria,” Gabbard said. “The first is the war against ISIS and other Islamic extremists, which Congress authorized after the terrorist attack on 9/11. The second war is the illegal war to overthrow the Syrian government of Assad.”
The case against Assad amounts to nothing more than cheap unproved assertions that Assad is "a butcher," that he used gas on his own people (ridiculous), and simply that he "must go." The overall level of deception, hypocrisy, and moral taint involved in what we have done and what we still do in Syria is a stain on the honor of America.
If there are reasons for fighting Assad with borrowed Chinese and Japanese money while our own borders are wide open, they need to be publicly presented to Congress so that it and the American people can decide whether this ghastly conflict is something that is worth the life of even one more American.
