If they play the “diplomatic immunity” card, their delegation will likely be sent home, our delegation will be called home, and Qatar will go on the terrorist list and all trade between us will be shut down.

Qatar is a crucial ally in the both the Iraq and Afghanistan war. The Al Udeid Air Base, near the capital, Doha, plays a critical role. the base has the longest runway in the Gulf and can handle 120 planes, and is located just 700 miles from Baghdad.

The only way that we will shut down “all trade” with Qatar is if those wars are ended.
