Israel has warned U.S. intelligence officials that Iran may be preparing to use chemical weapons, a claim that has caused serious divisions within the Donald Trump administration. Some U.S. officials take the threat seriously, while others suspect Israeli Prime Minister Netanyahu is trying to draw Washington back into a large-scale military operation. Gulf officials have also questioned Israel's assessment.

U.S. Central Command has reportedly developed plans for strikes as early as November 4, although Donald Trump has not yet authorized new attacks. Meanwhile, diplomatic efforts to reopen the Strait of Hormuz are ongoing alongside military buildup.
