Afghanistan. Everyone wants a solution but no one can even explain the problem.
That's because: It really isn't a real country. It is part of Pashtoonland, an arbitrary group of tribes living in the most worthless piece of real estate on the planet (unless they discover oil) which also takes in most of Pakistan. All of this region is made up of a lot of people who don't like each other very much except in their own tribe.... except, they dislike outsiders even more.
Their governments are corrupt. We underwrite all of them, which is why some of them like us, this week.
It is a Muslim country. Anyone foolish enough to want to change that will not come back alive. And, they have their nuts like all religions do. That was the last government called the Taliban. They want to become the next government, again. They will do that by making us leave. Anyone that helps them do that is their friend. Everyone else is their enemy......this week.
Having interjected ourselves into this asylum and not having had sense enough to leave after six months and "Mission Accomplished", we have inherited the keys to the building, otherwise known as "nation building". That is something we were not going to do. We were not going to do that in Iraq either. Or in Vietnam for that matter.
Did I mention Pakistan or the part about them having nuclear weapons?
This area is bordered by: India who Pakistan hates. Did I mention that India has nuclear weapons? China...ditto, nuclear weapons. Russia, double ditto, ie. lots of nuclear weapons and Iran, who wants nuclear weapons purportedly to destroy Israel who also has nuclear weapons, if they don't destroy Iran first.
So why are we there. To capture the guys who blew up the Twin Towers on 9/11, except we can't find them, but say we'll stay until we do? Meanwhile let's bring NATO into the picture.
You now have countries from just about every continent in play and all it takes is one miss step. And leaving is, after all.... a step. So is staying for that matter. Feel better now?
