The "antiwar" groups only mobilize when there is a chance to attack America. This is a perfect example of that.
That's right, but it could be even more strictly stated. They only mobilize to attack America when a Republican is in charge.
There were no massive protests when Clinton was bombing civilian targets in Kosovo, and the few protests which happened fizzled when the press would not cover them.
By contrast, there was a huge uproar over a few civilian casualties in Afghanistan. The protesters are merely radical leftist whores and the press are their pimps.
