A month after the U.S. and Israel launched airstrikes on Iran, President Donald Trump addressed the nation in a prime-time speech on April 1, saying the military operation was "getting very close" to completing its mission. Trump repeated some false and questionable claims we've written about before. Trump said the U.S. "totally obliterated" three nuclear facility sites in Iran last June. Experts and a classified U.S. intelligence report said the sites were damaged and Iran's uranium enrichment program was set back, but the sites and the country's nuclear capabilities weren't completely destroyed. The president said that Iran was "right at the doorstep" of "a nuclear bomb." Arms control experts have said that there's a lack of evidence that Iran was rebuilding its nuclear program before the U.S./Israeli military operation and that a nuclear weapon wasn't "imminent."
