No, it serves no purpose. The guy did way more than most Americans and now he's a lunatic. Why attack the patriot when you can attack the lunatic?
What kind of lunatic are you???
You have obviously never served...probably you should not comment....
Of course it serves a purpose, it helps protect the nation from those that are telling us that our men and women in uniform should not be attacking terrorists where ever they find them.
And doing so prevents a repeat of the whole "Viet Nam" episode where our troops were savaged by the liberal pundits and politians for beating the Communists until they begged for peace.
The purpose here is to never let the left repeat Viet Nam on a whole new generation of our military.
What better purpose is there?
