Even if this evidence is true, is it still the basis for the United States to declare war on Syria? Should it not be debated in Congress and military action done only after a Congressional vote authorizing military action? Is the US ready for the probable Syrian response which is likely to be a missile attack on Israel? Will the US support Israeli attacks on Syria and Iran? The Russians may very well be right. An American attack may lead to a catastrophe.
Any action should need Congressional approval.
Assad has provided safe harbor for terrorists for decades. He deserved what’s coming to him.
That said, the U.S. needs to make sure we aren’t backing worse. And I’m not at all confident that we are.
