The discussions center on a new aid package for when the current $3 billion a year expires in 2017. Sources on both sides expect the new deal to raise the figure to $3.6-3.7 billion a year, to assuage Israel’s fears about expectations of an unsatisfactory nuclear deal with Iran. Prime Minister Benjamin Netanyahu confirmed there were such discussions, but said he would keep campaigning against Iran. "There is no trade-off requiring I agree to this (nuclear) deal with Iran. The deal is bad and we will continue to oppose it," Netanyahu said.
