Patriotism = Unquestioning Barbarism?

Large sign on the back of a yellow Motor Carriers Services Incorporated semi truck on my way to work this morning (emphasis theirs):

Support Our Troops
Wherever We Are
[large American flag]
No Aid Or Comfort For
The Enemy - No Way!

This is wrong-headed in so many ways (including grammatical) that I don't have enough fingers even if I include toes.
