Wrong road to win in Afghanistan

A slow walk through history would tell just about any one that the continuing a surge in Afghanistan is, how should I put this? A big mistake.

I won't bore you with the history but in the short-cut version the Brits called it the "graveyard of empires". Alexander the Great had more problems there than he would admit while his army was there. The mighty Russians got their asses kicked until the sophomoric U.S. Representative, Charlie Wilson (Texas) found the means, however secretive, to get shoulder-rocket-launchers to the Afghani fighters. After 10 brutal years the Russians pulled up, retreated, and left the place admitting that too many Russian helicopters were falling out of the sky. Remember they were the "Super Power".
So what are we doing there? Adding another 36,000 troops, spending (choke) another $2 Billion a month, and for what?
If Bush/Cheney were pulling this we would be outraged, in fact, how is it any different?
I ask: "What is so important there that we must risk/kill another young soldier, marine, or airman for that place (Ok, apologies to the Navy Seals). Please show me/us the world what is so damned valuable that we must necessitate an even more brutal war than in Iraq.
This is from a former Marine.
