Since I don't know the mindset of the child and his position on the war, I'm unable to comment on that.
For sake of debate however, if this child felt moved to protest the Iraq war, then so be it. We all have that right, even a 10 year old.
I'm sure he did hear his parents discuss this death watch. Great. His parents taught this boy to pay attention to society changing issues that are simply wrong. Wrong not because of "politics", but wrong because of life being taken for no reason other than "politics".
The war is much more than politics. Millions now have an opportunity to be free. That is a noble cause and certainly worthy of the effort.
The only reason to protest against Iraq is all selfish reasons. I have yet to hear one valid non-selfish reason not to be there.
All of us will die, yet only a few will die with honor while attempting to free a whole society...or even 1 person. That is a true hero and may God Bless them all.
