How Many Afghan Interpreters?

Although I initially endorsed this petition when it appeared on Change.org...

I'm now beginning to wonder just how many Afghan interpreters we're going to need to save, and whether we may not need, for reasons of national security, to encourage some of these people to stay in Afghanistan. Will saving the interpreters turn into a disastrous effort to evacuate every pro-U.S. Afghani family into the United States, leaving a completely hostile country behind?

I don't know. This kind of thing is why I try to stay out of foreign policy.
