Muslims visiting the home country
Probably a number of them. But there are/were a good number of American businesses operating in Yemen. Haliburton being one.
Probably, but that should make O more willing to help them. Frankly, as a normal white male, what used to be thought of as a typical American citizen, I'm a nervous tourist. I don't think that in most countries my embassy will lift a finger for me under this Administration.
