The inability of the U.S. government to adequately train a cadre of professionals competent in foreign languages never ceases to amaze. Particularly with the war in Iraq, one would like to think that Arabic training is a priority for the military (and the rest of government).
I once attended a government language class with an agent from the Naval Criminal Investigative Service, who was getting a year of Arabic before being shipped off to Bahrain. That was actually commendable of the Navy, since junior diplomats typically get six months. The problem? Our class was being taught a Jordanian dialect, and the agent discovered -- after actually meeting someone from Bahrain -- that he couldn't understand a word they were saying.
Details, schmetails. Anyhow why worry, the Pentagon has announced the Language Corps:
Strategy Page looked at this idea when it was first rolled out a couple years ago under another name, noting that earlier proposals "never got off the ground." An obvious issue is that a volunteer corps likely isn't going to help with the military's lack of Arabic-speakers in Iraq.
