While it may be argued that kicking people out of a Fort on their own territory is a belligerent and ill thought out act, the response was excessive.

The strike on federal property was more than an affront - it was a portent of the violence by insurgents yet to come. I realize that anti-Americans like you don't care about such things but there are some of us who do.
