This car was spotted in Portland, ME, August 24th, 2011. The translation on the sticker says "Help from Allah and present victory."
In Arabic it says "Victory from Allah, and invasion soon." The word "FATTEH = Invasion" was used during Muhammad's era when he conquered areas killing people who did not submit to Shariah. After they were done, they would celebrate for the "FATTEH" of this country.
This bumper sticker was made for the USA, and was translated so it would sound good to the non-Arabic speaking Americans.
