You forget some things about the US military, and the way the Afghan struggle was fought last time around.
First, we have seen our share of the "enemy" wearing sheep\'s clothing in Viet Nam. Our gov. has most assuredly learned how to deal with these insurgents. There\'s no way you can go through something like that and NOT learn about it.
Second, Russia\'s enemy was armed, trained, and supported by the most powerful country on Earth, America.
No such luck for these guys this time around. They will be cut off and hunted down by the people that taught them their tricks.
Granted, they probably have some stuff up their sleeves, but, for the most part, it will be a totally different fight, altogether.
We have learned from our mistakes, and the mistakes of others, including Russia.
We may not be in as much trouble as they think.
