Just over 24 hours ago, I heard the news that Osama Bin Laden was dead. Some part of me is still trying to grasp that. Killing OBL was something that needed to be done, and I hope some people find a measure of peace in knowing of it. But nothing's really changed. There's still a war on.
Looking back over the past century of so, it seems the US has rarely gone more than a few years without being embroiled in some conflict, often for years. Believing that the nature of people will suddenly change is futile, so even if the combat zones we currently inhabit were evacuated of US service members, it is likely we will be fighting again shortly.
I do not see any dramatic reduction in the threats we as a country will face in the near future. I hope I am wrong.
