At present, Israel should focus on the Iranian nuclear challenge and the threats in the northern arena, and avoid getting dragged into another campaign in Gaza at less-than-optimal timing.
Israel should prepare for the collapse of the Vienna negotiations, even if such a scenario is less likely at this stage, and get ready for a broader diplomatic and other campaign for stopping Iran's technological nuclear progress based on close coordination with the United States and Biden Administration, and using the communication and collaboration channels established with it in political, military, and operational areas.
As part of its said preparation, Israel is advised to demand that the international community condition the Vienna negotiations with Iran upon the cessation of the latter's technological nuclear advancement. Israel should also raise the need for the United States to once again pose a credible military threat to Iran, and reiterate that "all options are on the table" (the last person to use this formula was President Obama).
