Trump was confident he could cut a deal with Iran that would stop it from obtaining a nuclear weapon. A significant topic of discussion at this year's Davos meeting was Iran's nuclear program. On January 22, Rafael Grossi, head of the International Atomic Energy Agency, told reporters in Davos that Iran is 'pressing the gas pedal' on its enrichment of uranium to near weapons grade. Israel and Iran clashed during the conference. President Isaac Herzog called Iran an 'evil empire' that spends billions to finance its military allies. New information about Iran's nuclear program was revealed on February 1 by the UK's Daily Telegraph.
