I do believe Muslims would be in danger from Americans after an terrorist attack in this country more so than the attack from thier own kind.
here is some thoughts i have had
this guy says the United States could face big attacks durning the mouth of Ramadan. im not a doc of this stuff and this is only my opinon but wouldnt you want to make it more omminous that saying "could" especially after saying we would?
we must also look at how extremist look at "Allahs punishment", remember back durning Katrina they said Allah was punishing America for bad policy and the city of homosexuals? im sure some are over there looking at the natural disasters in Buffalo, Hawaii, and to a extent Houston (Flooduing) as Allah's punishment.
lets hope our tax dollars are working hard for us and the FBI/CIA/NSA is working overtime to keep us safe. We should also keep in mind that Al Qaeda has a propaganda ring which is running overtime.
