They are contractors who get paid by and serving the US government.
The same US government's diplomat (and every other government) hires Pakistani staff and Pak security guards. The same way these guards get paid by the US and serve their employer.
Primitive tribals in the Arab land feel that Xi contractors are 15 feet tall, 200 kg gods who can push the Arabs left and right.
In Pakistan however we have not seen the 15 feet tall, 200 kg Xi-gods pushing Pakistanis around. May be we do not consider them gods. Do you?
These contractors can do what ever they want, but are they allowed to be above the law in any other country... if we go by ur logic, any country can hire private contractor and can have them involved in illegal activities in any country... but i guess this is fine by u as long as americans are doing it
and I believe in one Allah, unlike others who have every tom dick and harry as their god and they speak all the non-sense to protect their gods mistake
