Former President Donald Trump deemed “nuclear warming” the biggest concern the world faces when discussing the growing threat that Iran poses to the world.

Trump made the claim on the 1-year anniversary of Hamas’s Oct. 7, 2023, attack on Israel, an assault he argued should have never happened. The former president was asked whether he would advise Israeli Prime Minister Benjamin Netanyahu to strike Iran’s oil refinery or nuclear sites, prompting Trump to argue that “nuclear warming, not global warming,” is the biggest danger to the world.
