President Donald Trump went after Iran in his first major speech in Saudi Arabia, warning that Tehran must choose between never having a nuclear weapon or dealing with his wrath.

“If Iran’s leadership rejects the olive branch and continues to attack their neighbors, then we will have no choice but to inflict massive maximum pressure,” Trump said during an address to business leaders in Riyadh.

“The choice is theirs to make,” he added.

Trump asserted the Biden administration’s removal of some sanctions on Tehran as the chief method in how Iran financed terrorist organizations, including Hamas, which he argued led to the deadly Oct. 7, 2023, attacks on Israel.

Fox News Digital reached out to a spokesperson for President Joe Biden for comment on Trump’s claims.

“If only the Iranian regime had focused on building their nation up instead of tearing the region down,” Trump continued. “Yet I’m here today not merely to condemn the past chaos of Iran’s leaders, but to offer them a new path and a much better path toward a far better and more hopeful future.

“In the case of Iran, I have never believed in having permanent enemies,” he said. “Enemies get you motivated.

“In fact, some of the closest friends of the United States of America are nations we fought wars against in generations past,” Trump pointed out. 

It is unclear how Trump’s negative comments toward Tehran could impact ongoing nuclear negotiations with Iran. 

The Iranian representative to the U.N. Mission in New York did not immediately respond to Fox News Digital’s questions.
