YONI BEN MENACHEM -- Apart from strong statements by Hamas leadership against the migration plan from the Gaza Strip to Jordan and Egypt, initiated by US President Donald Trump, the terrorist organization has so far not taken any real steps against the plan. 

However, senior security officials fear that Hamas will disrupt the return of the hostages to Israel, which is scheduled to take place this coming Saturday, and there is a heightened alertness within the security establishment over such a possibility.

The Israeli negotiating team for the hostage deal and the ceasefire in the Gaza Strip is scheduled to leave for Doha this coming Saturday to discuss further implementation of the first phase of the hostage deal. Israeli security officials say that it will only discuss the completion of the first phase of the deal and not substantive issues related to the second phase, even though negotiations on the next part of the agreement with Hamas have already begun behind closed doors.

According to them, the discussion on the second phase of the deal will only take place after the security cabinet determines the government's positions on the issue. Hamas could "show muscle" and disrupt the release of the hostages scheduled for Saturday. The Americans are also taking this possibility into account.

As you may recall, Trump said in his last press conference with Prime Minister Benjamin Netanyahu that it is possible to reach the next phase, but there is no certainty that the deal will continue because "these are complicated people and in a complicated situation."

According to Israeli security officials, Hamas is well aware of the sensitivity of the Israeli public regarding the hostages, and it may take advantage of it and disrupt the release of the hostages on Saturday in order to send a message to the Israeli government and Trump that it will not agree to the American immigration plan.

Disrupting the deal could lead to renewed fighting in the Gaza Strip and a significant cut in the supply of humanitarian aid to the Strip. Israel still has major military leverage over Hamas, and the IDF has not withdrawn from the "Philadelphia Axis" area and the Netzarim Corridor.

It is still unclear whether Minister of Strategic Affairs, Ron Dermer, will already head the negotiating team that will leave for Doha this coming Saturday, or whether in the meantime Mossad head, David Barnea, will continue to conduct indirect talks with Hamas.

According to political sources, Netanyahu also wants to remove Shin Bet head Ronen Bar from the negotiating team, due to a crisis of trust with him that has only worsened since the October 7 massacre.
