StrategyPage reports on the completely predictable deterioration of the Afghan National Army:
As expected the Afghans are having a hard time maintaining the aircraft and vehicles they have received, mainly from the U.S., for their security forces. The problem is a growing number of these vehicles and aircraft are inoperable because of maintenance issues. Afghan officers complain that they cannot find or train enough Afghans to keep this stuff in running condition. Foreigners observe that corruption, low education levels, and stiff competition for skilled Afghans has meant that the Afghan military is unable to adequately maintain and repair the aircraft and vehicles they have.
You can’t engage in nation-building where there was never a nation, and you can’t muster a first-world military from third-world tribes.
