Nice try Omar! President Bush and our military is doing just fine!
In Vietnam they had similar caves (with several exits) dug into flat or only slightly rolling terrain, and we still often had to crawl into the caves to get the Viet Cong.
Afghanistan presents some of the same challenges as Vietnam, except that instead of hiding in the jungle your enemy hides in caves or niches in the rocks. In both cases, he is used to living and fighting with not much more than he can carry on his back, and will fade away when confronted with superior firepower only to re-emerge for a surprise attack when the odds look better.
We had most of the advanced ground-fighting equipment in Vietnam, including infra red sensors, laser gun sights, fuel-air bombs, carpet bombing, etc. and were still fighting after years.
A ground war is not a good idea. If all of the current bombing, a Northern Alliance assault, plus attacks by various special forces groups works, and we take Kabul, Kandahar, Herat and all the other cities, and have regular armored patrols on the highways -- we will be at the same point as the Russians, and it didn't turn out well for them because the hard-core Afghan fighters will play hide and seek for years and not be concerned about dying if they can pop out of some rocks and kill a few "infidels".
I hope we do get all of the terrorists and make them pay, but it is not going to be fast and easy. Afghanistan is no Iraq, which was the perfect place to fight a war with high-tech weapons and air power.
