Again, it would be nice if someone could kindly define on exactly which grounds they confidently assume this war in Iraq to be "illegal". Because I have not been able to find any valid grounds so far. And public opinion is most surely irrelevant to any such definition.
I hear these "illegal" accusations from people who have,

A. Never served in an Army
B. Have some bias against an Army (like was kicked out)
C. Have some bias against the Armies government
or D. Have no idea how war works, or what a soldier is expected to do
