Obama's first big mistake?

I guess to err is human and Obama is no exception. I wonder if it was the extraordinary achievements of the existing troops that convinced Obama that another 30,000 would do even better?!? The truth is the larger the troop size, the stronger the resistance and the larger the mistakes they make, not to mention the increased losses of lives on both sides. And by the way, what did the troops achieve in 8 years that makes Obama believe they are going to achieve a lot more in 18 months and withdraw troops? Are we too dumb and too blind to see the light? What can be achieved in 18 months? Aren't we thinking about way too much of ourselves and our abilities to transform the rest? What do they know about that country, its culture, its people, its history? By the time they have learned a bit about Afghanistan and get used to the terrain, it will be time for them to return.

What is gonna happen in 18 months? I hate to be among the first to say this, but we will have made a bad situation worse. You can't fight an enemy that you don't even know well enough. Military expansion and troops excalation is not the solution, but who will listen?
