The objective conditions, including diplomatic, are different than Arens describes. They are that Israel's degree of settlement and extent of restrictions had reached a critical mass where the reality of suppression of Palestinian civil rights, conflicted fundamentally with Israeli, US, and humane values and law. The second objective change is the continued presence of an offer at normalization of relations requiring moderate fundamental compromise on the part of Israel. This offer, IS the prize, the extent of rational Israeli presence given population demographics, need, and need for security. Its important to distinguish between an observation and a rationalization. "Israeli civilians experienced harrassment and violence" is an observation. "Israel must suppress in order to protect" is a rationalization.
