Explosion of a hydrogen bomb
Explosion of WTC
The US goverment didn't do this to its people, the JEWS did this to Christians, they ram two planes into your Christian towers, they told your Christian soldiers to go fight for them so that they can have their ancient lands of Khazaria back. The JEWS own everything, inside and out, your entire life belongs to jews and you are nothing but a statistic.
ROFL @ people in this world. GO USA!!!!!!!!!!!!!!!
