There is a saying that "those who don't learn from history are doomed to repeat it". That adage definitely applies to the US presence in Afghanistan. The country is the devils favorite vacation spot We have no business being there. Other countries have tried to conquer or tame the Afghans and have failed.
The latest incident of a crazy US soldier going house to house and killing children and women is incomprehensible. It will give rise to retaliations against other US troops who are just trying to do their job.
For somebody as smart as Barack Obama I am puzzled as to why he just doesn't call it a day and get out of this miserable piece of real estate immediately and let them kill each other. GET OUT NOW!!!!!!!!!!
