"I believe that the US should offer a program that teaches Arabic to US military members that are separating from the military.
"
Well, that would work....in about three or four years. Learning a language well enough to translate tapes of spoken Arabic ain't easy. I know. I was a Russian linguist in the USAF. After our year of full-immersion language training, I was ready to do a good job about two years later, and I was #1 in our class.
Your idea is an oversimplification of the task.
There is no easy way.
Simply put, we need to refrain from using Arabs to do the job, as their allegiances are more likely to be toward those we investigate, than would be any American born person.
We need people to do this with last names like Smith and Jones.
