Tulsi Gabbard is being thrashed today in the Trump Is Always Perfect camp for saying that He is supporting AQ. If she had expanded the accusation to include actions taken in the Obama administration she would have been exactly correct.
The Saudis, the Israelis and their acolytes among American neocons like the late, sainted John McCain, Sheldon Adelson, Lindsey Graham, Joe Lieberman, John Bolton and Pom Pom have long succeeded in using the madcap US policy of regime change in Syria as an excuse to fund jihadi groups in Syria. There is a wide variety of these but the most obvious are the al-nusra front and hayat tahrir al-sham, both of which are branches of AQ in Syria.
Both CIA and the US armed forces have been and still may be supplying and funding these groups. She was right. She simply needed to explain herself better and not try to pin the blame solely on Trump who is largely an "absentee landlord" with regard to policy in the ME. He has no policy in the ME. Adelson, Natanyahu and Lindsey Graham have policy in the ME, but not Trump. pl
