The big problem with this Abu Dhabi thing isn't the Arabic/Muslim/terrorist/whatever aspect, though it certainly doesn't look good for the president or his party. The big problem with stuff like this, the big question, is whether America wishes to continue with the fiscal policies that lead to foreign interests owning large chunks of their country.
I don't see how this huge debt/expenditures & foreign-ownership stuff will look at all positive in the future. Especially when the taxpayers recieved little to nothing ou of the record-shattering expenditures.
