Iranian President Hassan Rouhani on Tuesday vowed to stay in the Iran nuclear deal shortly after President Donald Trump announced that the U.S. will withdraw from the multinational pact, a decision that ignited outcry and concern from fellow world leaders.

Rouhani, in a blistering televised address, criticized the U.S. as a country that never adheres to its commitments and accused its people of having always adopted a hostile approach.

By exiting the deal, America has officially undermined its commitment to an international treaty, he said.
