Saudi Crown Prince Mohammed bin Salman warned on Wednesday that if Iran acquires nuclear weapons, "we have to get one," in the most direct public indication so far that the kingdom will not stand by if Tehran breaks the nuclear weapon threshold. 

In a wide-ranging interview with Fox News that aired on Wednesday night, the crown prince widely called MBS said that Israeli-Saudi normalization talks are ongoing and making progress. 

The hour-long interview, the first for MBS in English, was designed to address a Western audience. His emphasis on Iran and Israel come as Riyadh is asking Washington for security guarantees to serve as a prerequisite for reaching an agreement with Israel. Saudi Arabia does not have formal diplomatic ties with Israel since the country was established in 1948. Among its requirements is the establishment of a civilian nuclear program on its soil, including uranium enrichment, according to multiple media reports. Riyadh also wants a mutual defense pact with the United States and significant arms deals. Iran and Saudi Arabia, longtime regional foes, agreed to normalize relations in March.
