The leaflet says in Dari (Afghan Farsi) first and then Pashto:
"The coalition of nations is here to help you"
and on the bottom
"The coalition of nations is here to help the people of Afghanistan".
Many rural Afghans can't read to begin with. All they will see is this funny picture of an Afghan shaking hands with an American soldier. They will be enraged and rip it up because all they know is that the Americans are killing them. They have no idea why. Also, the language is very unnatural, so those who can read will not take it seriously at all.
