You can boycott any American company, or foreign company except one. You can protest any government's foreign policy, except one.

How is it that we could believe that three murdered Israelis justifies the genocide of over 2,200 Palestinians? Where did we see that before, and did it not warrant the Nuremburg War Crimes Trial?

In retaliation for the killing of one Nazi officer 642 French civilians were massacred.
