I think that Banksy's art is trying to make a statement. I think he might be taking the familiar images and interpreting them in a way that shows the negativity of war becoming almost commonplace.
I thought the graffiti of the guy with the flowers was interesting. One of my friends that lives on my dorm floor showed this to me a few weeks ago. We both thought it was really funny and kind of ironic that the guy is standing and holding the flowers like he's going to throw a grenade or something. I was also drawn to the flowers because they were the only part of the graffiti that was in colors other than black and white.
