If Barack Obama Made a Really Stupid Decision About US Troop Deployment: Wouldn't We Hear About It?

Something that Senator Lindsay Graham would describe as “the dumbest idea in the world.”
What I am describing is something that would put the US into conflict with a North Atlantic Treaty Organisation member.
Something which should have had congressional approval before being implemented? Something along the lines of funding an organisation which the US State Department lists as being a terrorist organisation.
Yet, that is exactly the situation that happened in Syria. After all the person who was president when the American-led intervention in the Syrian Civil War was Barack Obama.
There are a lot of things which stink to me about the US coverage of this event. The main one is the sudden sympathy for the Kurds.
But even more bothering is that Donald Trump is being blamed for something which sits squarely on Barack Obama's shoulders.
Yet even people who would have attacked Barack Obama are criticising Trump for this situation.
