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?
I can't believe you USMC folks are not ripping this POS a new one....hell I am an Army Airplane Driver...and we would piss on the ole mans leg while he was in the shower...
