They've been infuential in steering the Iraq leaddership away from having bases there...majorly so.
No matter how the picture is painted, 'Obama failed' to establish a US presence there....which was more than understood when we went in there.
Iran sees this as thier victory over the US. Calking one more up in their court.
Couple this with all the other "victories" this administration allowed Iran, there is no doubt that radical socialists and islamists are working together.
The socialists give the islamists the Middle East while the islamists create the turmoil and spike required to collapse the Western nations so they can be reorganized under a single UN-like authority.
