If that happened in the USA: Everyone would have to stay inside for months, the stock market would crash, and it would trigger anarchy. But that can't happen since most modes of communication are monitored under the Patriot Act.
I don't really understand those islamic lunatics.. Destroy your own country!!. I feel sorry for them folks. I don't mind if those bastards blow themselves up(matter of fact i would be happy), but take others(innocent people) with them that's a no no
The only orginised groups of terrorists that could do such a thing to US are ISLAMIC TERRORIST ORGANISATIONS. May be their members have missed the part in the quran that teaches; Peace, Tolerance, and Nonviolence..... the imams probably forgot to tell them that muhammad "never ever" used violence (at least that's what my muslim friends belief in, muhammad was the most noble person on the planet who hurt nobody.... be careful though if you disagree on that with them, they will surely get offended.)
