These people aren't coming to Israel in order to propose a constructive way to get a peace deal signed between the Palestinians and Israel. These are foreign nationals who hope to stage demonstrations in support of an organization, Hamas, which is in a self-declared war against Israel, that condones and carries out terrorist attacks against civilians, and that swears to continue its "struggle" until the demise of Israel. Israeli citizens, who have to bear the consequences of any Israeli policy, have the right to demonstrate for or against those policies and exercise that right every day. Foreign nationals do not have the "right" to engage in political discourse in a country that is not their own. These so-called activists are going to get a lesson in national sovereignty when the sovereign State of Israel sends them back home. In every other country in the world, tourists and other non-citizens who engage in political activity are promptly deported. Israel is like every other country, whether these condescending, self-righteous individuals accept it or not.
