Whether Iran, Syria, or the Palestinians thought up the idea of having refugees march into Israel, this is a PEACEFUL protest in the Gandhi style. Gandhi succeeded in his efforts and became an international saint. At the present, the Palestinians will fail, since they are trying to come in from OUTSIDE the country (as far as Syria and Lebanon are concerned). But once the UN declares the West Bank Palestinian territory, such protests in the West Bank, for example entering area C, will be extremely effective. Learn from your experience, pals.
