There was never any good reason to get involved in Syria, just a few bad ones. From Ted Snider at antiwar.com:
At the close of 2018, President Donald Trump announced that American troops were being withdrawn from Syria. By the open of 2019, National Security Advisor John Bolton and Senator Lindsey Graham were saying that there would be no withdrawal before a full defeat of the Islamic State and other objectives were achieved.
As usual, the tune being played by the White House is more cacophony than symphony, and no one knows when the troops will be withdrawn from Syria. The notes played have included everything from immediately, to a month, to several months to not until were done.
Whenever it is to be done, the withdrawal of U.S. troops has brought near unanimous criticism from the mainstream media. The alternative media has had several very good articles on the appropriateness of the withdrawal since all of America’s objectives in Syria have been realized to the extent they can be realized. Trump, himself said this when he said, via Twitter, “We have defeated ISIS in Syria, my only reason for being there. . . . ”
But, it is not true that the defeat of the Islamic State was the only reason for American troops being in Syria. The reasons have ranged and changed from regime change, the Islamic State and chemical weapons to Iran. And most of the alternative media articles have missed the more important point that, if America’s objectives have been realized, it is only because they were never problems in the first place. If the obstacles to peace are gone, it is only because they were never there. If the troops can be withdrawn from Syria, it is only because they never should have been there.
