Israel must lay low, and refrain from public, threatening diplomacy vis à vis the U.S. administration, whereby its views are presented in advance by the media. Instead, it is advised to pursue quiet, intimate dialogue based on the shared view that Iran must not be allowed to have nuclear weapons, while relying on the existing robust channels of cooperation in areas such as intelligence, defense, and operations between the two countries, and strengthening them.
In order to build trust with the incoming administration that will enable it to impact U.S. policy, Israel must display constructive, practical views, and avoid threatening to opt for the military alternative. The chances of implementing an Israeli military option against the U.S.'s better judgement is low in any event, and is virtually illogical at present, since the return to the JCPOA keeps Iran's nuclear program far enough away from breaking out to nuclear arms in upcoming years.
The negotiations between the United States and Iran on the return to the nuclear deal are expected to be complex, may run into difficulties, and are likely to take couple of months at the very least. Thus, a window of opportunity may open for profound dialogue between Jerusalem and Washington on this issue, during which Israel should strive to convince the Biden administration of the advantages of a gradual, cautious approach to Iran, while setting benchmarks and maintaining leverages vis à vis the regime in Tehran. During the dialogue with the U.S. administration it is important to prioritize the nuclear challenge (including nuclear capable missiles) while also discussing, simultaneously but separately, collaborations to inhibit other regional threats to Israel posed by Iran, particularly along the former's northern border.
Israel is also advised to avoid seeking to create a shared regional front with the moderate Arab states against the U.S. administration's policy on Iran (as opposed to an anti-Iranian front). Such a move may be perceived by Washington as defiant, and, in any event, the Arab states are expected to align themselves with the Biden administration in light of their security's profound dependence upon American guarantees.
Finally, to allow U.S.-IS relations to focus on Iran, it is vital that Israel remove any other obstacle and dissipate any further tension with the incoming administration. As part of this effort, and in light of Washington's extreme sensitivity with respect to the great power competition, Israel must conduct itself with full coordination and transparency vis à vis the United States with regard to its relations with Russia and China to ensure that it meets the American standard. This way, the U.S. administration would be able to determine that China's activity in Israel and Israel's relations with Russia do not pose any risk to U.S. interests.
