So the Department of Homeland Security has published a report warning that the US might see increasing numbers of right-wing terrorists in the next few years.
Here's the key paragraph:
The DHS/Office of Intelligence and Analysis (I&A) has no specific information that domestic rightwing* terrorists are currently planning acts of violence, but rightwing extremists may be gaining new recruits by playing on their fears about several emergent issues. The economic downturn and the election of the first African American president present unique drivers for rightwing radicalization and recruitment.
I have two responses.
1) Duh. Of course.
2) No, this doesn't mean that Obama thinks all Republicans are terrorists.
PS - Read the report. It's only like seven pages long. And it's a little bit interesting, even for non-specialists.
