Freedom of speech is exactly what is at stake here. US citizens and the companies they run have the right to voice their displeasure with their dollars or the spoken word. If I want to send a message to a company by not purchasing it's produces that's my privilege and it has been used many times before on an international stage. Ask anyone about dolphin friendly tuna or pet treats or baby formula from China (just about any product from China). Words are cheap, countries really pay attention to their cash flow. Israel (and Christians) has been using the idea of the "Holy Land" since the crusades and sometime not so subtly displacing Palestinians at will. Maybe if they face the prospect of being forced to deal honestly they would find a solution to the question of Israel's existence. A suppressed majority never stays suppressed. Ask S. Africa.
