The premiers policy of treating the terror group as a partner, at the expense of Abbas and Palestinian statehood, has resulted in wounds that will take Israel years to heal from
For years, the various governments led by Benjamin Netanyahu took an approach that divided power between the Gaza Strip and the West Bank bringing Palestinian Authority President Mahmoud Abbas to his knees while making moves that propped up the Hamas terror group.
The idea was to prevent Abbas or anyone else in the Palestinian Authoritys West Bank government from advancing toward the establishment of a Palestinian state.
Thus, amid this bid to impair Abbas, Hamas was upgraded from a mere terror group to an organization with which Israel held indirect negotiations via Egypt, and one that was allowed to receive infusions of cash from abroad.
