Fifth Fleet
I've got lots of friends out in Qatar, and if faced with the choice would choose
Qatar over Ryanair.
I also don't think that Qatar will suffer the same fate as Egypt, Bahrain et al.
But don't kid yourself that having the US armed forces on your doorstep will stop any uprisings.
Bahrain is strategically more important to the USA then Qatar. It is home port to the USN Fifth Fleet. And I don't see the American's rushing in to help. They could be doing things behind the scene, but we'll never know.
You only have to look at the US actions in Libya, they can't wait to hand over command of the military action, lest they be seen to be intervening in a Muslim/Arab country.
