Decision-Making Authority in US-Israel Relations: Iran and the Dynamics of Imminent Conflict

By Elijah J. Magnier

The prospect of confrontation with Iran now extends beyond military and diplomatic arenas, encompassing perception, signalling, and the complex distribution of authority among allies. Israeli Prime Minister Benjamin Netanyahu’s efforts in Washington to persuade US President Donald Trump to shift from diplomacy to confrontation have implications that surpass bilateral coordination. Should the United States transition from negotiation to open conflict, the resulting perception could undermine the American administration by suggesting that Israel exerts decisive influence over US decisions to enter war. This dynamic projects an image of the United States, the world’s most powerful state, being guided by a smaller ally located thousands of kilometres away. Consequently, critical questions arise regarding who determines the rationale for US military engagement and whose interests are ultimately prioritised.

This issue reveals a more complex reality within the United States. Decision-making in Washington is distributed among the presidency, the Pentagon, intelligence agencies, and Congress. War results from the interplay between these institutions, in which political signalling may encourage confrontation while military planners exercise caution about escalation. Intelligence agencies may highlight risks even as political leaders seek strategic advantage. Although congressional authorisation is formally required, recent conflicts have often proceeded under executive authority. Thus, the decision to initiate war arises from the intersection of institutional power, political calculation, and perceived credibility. The resulting uncertainty in these internal dynamics contributes to perceptions of unpredictability from the outside.

During the Trump–Netanyahu meeting, Israel requested additional offensive and defensive equipment. This request raises questions regarding the necessity for further military hardware, given President Trump’s stated emphasis on negotiations and Netanyahu’s claims of having concluded conflicts in Gaza, Lebanon, Yemen, and Iran. Despite these assertions, Israeli military operations and casualties continue among Palestinians and Lebanese in these regions.
