It's not Turkish, Kurdish, or Afghan illegal aliens raping, credit-stealing, DUI-killing and MS-13 butchering across America. Defend OUR borders, not Syria's!
There is a reason we can get out of Syria now. Us pulling out turned into a Mexican standoff between our enemies with us out of theater. No power vacuums to be filled by unknown evil quantities. Erdogan is left with his proverbial pecker in his hand given Syria (armor), Russia (air cover), and the Kurds (infantry) stand there against him and the EU and USA are cutting him off. Iran loses their land bridge to Hez-Ebola. The Kurds have to play nice with Syria or they will get slaughtered by Turks. A very nice Mexican standoff with out us in the middle.
Give POTUS some time to work his magic in Afghanistan. He has been beating the Taliban and it’s leadership silly after they pulled that for political advantage attack/killing pre scheduled talks. They will not doubt his word next time.
As far as troops in Saudi, the Saudis are literally incompetent. They will pay big bucks for a large base there and have a well located safe base of operations if it ever comes to it in the ME would be my guess.
Iraq... no clue as to a plan but I am sure there is one.
