Good idea. That's why we currently offer a $25 million dollar reward for him:
If you want results, divide the millions between everyone who lives within one block of where al-Zarqawi dies. Then tell everyone how much money they would win. Yeah, win.
The psychological impact will be a passive support of Americans. Then later, self justifications -- they're not traitors to the cause, they really like Americans.
Have American PR firms do lotto type ads -- asking Iraqi women how they would spend their share of the reward. "How would your family spend $3,000?"
Trust me, for many that's more than a years pay, and they'll help. Walkin' around money -- dreams of cold cash, and dead terrorist. As a perk, because no family would receive a huge sum, they would convince themselves they wanted al-Zarqawi caught.
