Trump defends US interventions abroad ahead of 'big decision' on Iran: 'Settling years of unfinished business'

President Donald Trump issued a stern warning Tuesday for Iran to make a deal soon or face severe consequences for its pursuit of a nuclear weapon.

"I have a big decision to make: Will a deal be made with Iran that lets them rebuild and create a far greater country than it ever was before – maybe one of the greatest in the Middle East or even the world?" Trump told the United Nations General Assembly in his morning address.
