The Obama administration justifies an easing of Iran sanctions on the grounds that they can be tightened again if Tehran violates its side of the deal. History suggests otherwise.

Hamas declared yesterday that it won’t release more hostages “until further notice.” Given the timing and wording of the announcement—several days before the release was supposed to take place, and speaking of a delay rather than a halt—Ron Ben-Yishai concludes that it is a negotiating tactic, aimed at “creating a temporary crisis to gain leverage.” Therefore, writes Ben-Yishai, “Hamas may reverse its decision by Saturday.” He adds:

Israel cannot afford to concede to Hamas’s demands beyond what is already outlined in the agreement, as doing so would invite continuous extortion throughout the negotiation process, further delaying hostage releases.

The group sees the public outrage and growing calls for action following the release of hostages in severe medical condition as an opportunity to extract more concessions. These demands include not only a rapid start to negotiations on the next phase of the deal and an end to the war but also smaller, immediate benefits, particularly improved conditions for displaced Gazans.

Beyond these tactical objectives, Hamas has another goal—one that Israelis do not always recognize: inflicting psychological pain on the Israeli public. The group benefits from, and perhaps even draws strength from, the anguish and emotional distress in Israel, as well as the testimonies of freed hostages detailing the abuse they endured. Hamas wants these stories to be heard—not only to pressure the Israeli government but also because, in the eyes of its supporters, Israel’s suffering is its ultimate victory.
