. Kerry and Hagel are now in, but apparently Biden's star is ascending too, while all sorts of other folks are rotating to new jobs, unpacking their offices, or heading back to private life to pen memoirs. You might think this was a great opportunity for fresh thinking and renewed energy, but what it really reveals is how our approach to staffing foreign affairs may be the worst of all possible worlds.

For starters, the United States has a relatively small civil service. Compared with other countries, a relatively large percentage of top government jobs are held by presidential appointees. The result: top jobs in the State Department and Pentagon are handled not by career foreign service officers or experienced bureaucrats, but by partisan appointees who rarely last more than a couple of years and then return to private life. Not only does this mean tremendous turnover whenever the White House changes hands, it means we are constantly bringing in people who lack experience or who are not up to speed on current issues.
