WASHINGTON—President Trump signed what he called a ‘historic’ Iran nuclear deal Tuesday, but officials confirmed the document is identical to the 2015 agreement he once deemed ‘the worst deal ever.’ The only change: the title now reads ‘Trump Iran Nuclear Accord.’

‘He thinks it’s new because we switched the font,’ said Deputy National Security Advisor Mark Lassiter. ‘Iran agreed to call it the Trump Deal, so everyone’s happy.’
