Saudi Arabia is trying hard to make Qatar abandon its warm embrace of the Muslim Brotherhood. The fact is, however, that the plan may fail. The limited leverage the Saudis once employed is slipping. Qatar traded more with Singapore in 2012 than it did with Saudi Arabia, the United Arab Emirates and Bahrain! Qatar has markets for its natural gas in the U.S. and Asia, and a rolodex of overseas investments like Volkswagen AG (VOW) and Barclays Plc. Basically, Qatar can resist the diplomatic pressure its feeling because of its relationship with the MB.
