While those countries are certainly safe havens and breeding grounds for terrorists, the research actually points to other areas in the Middle East as the most prominent for financing, support, messaging, etc. I suspect that's why some people, regardless of political association view the Obama administration and now Trump's administration as faltering on this front. How any serious attempt at vetting Islamic terrorist groups excludes Saudi Arabia is mind boggling. Yet administration after administration continues to look the other way due to political interests, petrodollars and old fashion cash money. Par for the course for any administration no matter Democrat, Republican, Liberal, Conservative.....
This is very astute
