Problem Solved
I thought up something that might help the English out of their handgun dilemma.
Their handguns are too old and the country is too broke to afford new ones. The solution is the same as that used to deal with their domestic handgun problem.
The English can apply to the United Nations and pass a resolution to have handguns banned, worldwide. When they do that, the Taliban and other killers will cease using handguns, for fear of the legal repercussions. Problem solved!
This same rational has worked in dealing with the criminal element within England. As I understand it, handgun violence is now reduced to a mere historical phenomena, due to the wisdom of English legislation.
I see no reason why we cannot get the United Nations resolution passed, and then send Harry out into the field in Afghanistan armed with a friendly smile and perhaps some candy bars, to win over the hearts and minds.
After all, mere civilians like us have no reason to own handguns. Why does he?
