So I'm up to the point where I'm attempting to hold my ground in that big fancy hotel.

Prior to that they were passing through a night club and (I think (had my speakers too low)) the guy who they were going in deeper to save came over the intercom real quick sounding as if he had gone mad and wasn't taking his predicament very seriously.

Then I flashed back to the very opening of the game where they were fighting copters....musslim extremists most certainly don't fly choppers like that.

Then I remembered how the three of them were delivered by plane to a city notorious as a plane graveyard due to the violent sand storms.

So..

...here's the question...

(and I don't mind the spoiler myself - I feel a tad silly for taking so long to put two and two together, actually)

...Dubai is how the government assassinates men trained to well to easily be assassinated by any other means?

The game is 6-8 hours long, you'll beat it before you get a coherent short answer here.
