Appeasement in a political context, is a diplomatic policy of making political or material concessions to a (potential) enemy power (or powers) in order to avoid a threatened conflict.
.... Directly contrasting US President Barack Obama who praised the agreement as opening a "new path toward a world that is more secure," Netanyahu – speaking at the weekly cabinet meeting -- said the world has become more dangerous as a result. "What was agreed last night in Geneva is not a historic agreement, it is a historic mistake," he said.
"Today the world has become much more dangerous because the most dangerous regime in the world took a significant step to getting the most dangerous weapon in the world."
"This is a bad deal. It grants Iran exactly what it wanted - both a significant easing in sanctions and preservation of the most significant parts of its nuclear program," an official in Netanyahu's office said.
Netanyahu's sentiments were echoed by Defense Minister Moshe Ya'alon, who called the deal a "historic mistake" and a "surrender to the Iranian charm and smiles offensive, and to Iranian fraud, which is aimed at gaining time, without the Iranian nuclear program being substantially harmed."
The deputy speaker of parliament, Likud MK Moshe Feiglin, said on Saturday the interim agreement signed between Iran and the Western powers was tantamount to the Munich Agreement of the late 1930s.
“Like Czechoslovakia at that time, which was not party to the discussions that effectively sentenced it to death, Israel today watches from the sidelines how its existential interest is being sacrificed by the Western powers,” Feiglin said.
Feiglin said that entrusting foreign powers to secure Israel’s defense interests is “disastrous” and “much worse than that which led to the Yom Kippur War.” The lawmaker called on the Israeli government to declare an immediate end to all contacts with the West over the Iranian question and to make clear that it would not be bound by the agreement signed.
Knesset member Eli Yishai reacted Sunday morning to the deal: "the world's countries only saw the economic interests of the deal, and not their obligation to the security of Israel."
He stressed that Israel "has to no one to trust besides god and ourselves".
