The U.S. military is packing to leave Afghanistan - pulling up airfields, tearing down bases, disassembling Humvees for transport. Over the next few weeks, 23,000 troops will fly home, leaving 68,000 troops who will stay until 2014. The looming question, though, is: After 11 years, more than 2,000 U.S. military fatalities and at least $1 trillion in expenses, what are the United States and NATO leaving behind? The answer is bleak: Afghan security forces totally incapable of operating on their own, as the U.S. military quietly acknowledges. And a government so corrupt and ineffectual that, as the Army said in that report to Congress, it bolsters insurgent messaging." In others words, great PR for the Taliban. Since 2002, the United States has spent $43 billion to train the Afghan military and police. It plans to spend $11.2 billion more this year, and the military has requested another $5.8 billion for 2013. Now the training mission acknowledges that none of the Afghan forces are ready to fight on their own. The highest rating for trained Afghan forces today is "independent - with advisers." Only 7 percent of Afghan army units are capable even of that. That's just one in a nest of problems. Another big one is illiteracy. The special inspector general for Afghan reconstruction, in a recent report, said the literacy rate of Afghan security forces "as a whole is 11 percent." In almost every measurable way, the training mission is losing ground. Aren't we in the same position as the Soviet Union 30 years ago - pursuing a Sisyphean task, inescapably destined to fail?
