What did Trump do differently to Obama on Iran?

US President Donald Trump is touting a new peace deal with Iran, with Vice-President JD Vance saying Tehran’s nuclear programme has been “comprehensively destroyed”.

But former President Barack Obama says any new agreement is unlikely to be “significantly different” from the deal he struck with Iran in 2015.

The BBC’s Gary O’Donoghue takes a look at the contrasting approaches of the two presidents.
