Vice President JD Vances arrival in Israel on Tuesday comes as some Trump administration officials are concerned that the fragile ceasefire between Israel and Hamas could fall apart, sources familiar with the matter told CNN.

Vances presence in the region is meant, at least in part, to ensure Israeli Prime Minister Benjamin Netanyahu remains committed to the US-negotiated deal as some Trump administration officials worry he could work to thwart it.

One US official characterized it as Bibisitting. Another framed it as a show of force from the highest-ranking person after the president himself to make the administrations view clear that the ceasefire needs to be durable enough to outlast inevitable skirmishes.

The sources added that the general belief among US officials involved in the negotiations is that the truce is most threatened in the short term, which is why the trip needed to happen so soon after Trumps visit just last week.

The concerns reached new heights after Israel accused Hamas of carrying out an attack over the weekend that killed two IDF soldiers. Israel responded with waves of airstrikes that killed dozens of people in Gaza.

US officials worked to minimize the fallout of the strikes and ensure the ceasefire was not threatened, the sources said. And while Israel and Hamas each accused the other of violating the deal, both sides ultimately reaffirmed their commitment to the truce.

Trumps Middle East envoy, Steve Witkoff and son-in-law Jared Kushner, the key US architects of the deal, are also in Israel this week as the administration begins to work on the longer-term goals of the presidents 20-point peace plan for the region.

While there, Witkoff told Israel the countrys response to violence from Hamas needs to be proportionate to the violation, according to an Israeli source familiar with the matter. Witkoff also emphasized that the next 30 days are crucial for the deal to hold and for talks to enter the second phase, the source said.

The Israelis, meanwhile, are ramping up pressure on the US to demilitarize Hamas before talks move on to the reconstruction phase, an Israeli official said.

All of this comes as Trump himself has argued both privately and publicly that Sundays attack on IDF soldiers wasnt the work of Hamas leaders but part of a rebellion. He has said that some members of Hamas got very rambunctious, but he believes the group is still committed to the truce and negotiations, the sources said.

Trump did, however, threaten to have the group eradicated if ultimately necessary.

据知情人士向CNN透露，美国副总统JD·万斯（JD Vance）于周二抵达以色列之际，一些特朗普政府官员正担忧以色列与哈马斯之间脆弱的停火协议可能破裂。

万斯在该地区的存在，至少部分原因是为了确保以色列总理本雅明·内塔尼亚胡继续遵守美国斡旋达成的协议，因为一些特朗普政府官员担心他可能会设法阻挠该协议。

一位美国官员将其描述为“比比坐镇”。另一位官员则将其解读为“总统之下最高级别人物的武力展示”，意在明确传达政府的立场：停火协议必须足够持久，以“经受住不可避免的小规模冲突”。

消息人士补充称，参与谈判的美方官员普遍认为，停火协议短期内最可能受到威胁，这解释了为何需要在特朗普上周刚刚结束访问后如此迅速地安排此次行程。

以色列指控哈马斯在周末发动袭击，导致两名以军士兵丧生，此事引发空前担忧。以色列随即发动多轮空袭作为回应，造成加沙地带数十人死亡。

消息人士称，美国官员努力将空袭的影响降至最低，并确保停火协议不受威胁。尽管以色列和哈马斯互相指责对方违反协议，但双方最终重申了对停战的承诺。

特朗普的中东特使史蒂夫·维特科夫（Steve Witkoff）及其女婿贾里德·库什纳（Jared Kushner）——该协议的美方核心设计者——本周亦抵达以色列。与此同时，美国政府正着手推进总统提出的20点中东和平计划的长期目标。

据一位熟悉此事的以色列消息人士透露，维特科夫（Witkoff）在访问期间向以色列表示，该国对哈马斯暴力行为的回应应与所受侵害程度相称。该消息人士称，维特科夫还强调，未来30天对于维持协议和推动谈判进入第二阶段至关重要。

一名以色列官员表示，以方正加大对美施压力度，要求在谈判进入重建阶段前解除哈马斯的武装。

消息人士称，特朗普近期在私下及公开场合均提出，周日对以色列国防军的袭击并非哈马斯领导层所为，而是一场"叛乱"的一部分。他表示哈马斯部分成员"变得非常躁动"，但仍相信该组织致力于停火与谈判。

然而，特朗普威胁称，若最终必要，将彻底“铲除”该组织。
