From what I've been reading, the bill grants the DoJ power to combat sites outside of US jurisdiction.

See title I sec 102. http://thomas.loc.gov/cgi-bin/query/F?c112:1:./temp/~c1124uh...:

Is this only a piece of the larger picture?

edit: On further inspection, it appears as though title 2 does in fact grant powers for combatting domestic sites as well.

Or at least the language isn't explicitly speaking to foreign websites.
