In 2020, Trump brokered the Abraham Accords, which secured the historic normalisation of relations between Israel and two Arab nations, the United Arab Emirates (UAE) and Bahrain.
Sudan, Morocco and Kazakhstan have since also signed the accords.
Saudi Arabia has not so far responded to Trump’s remarks.
And it was not immediately clear if the condition of joining the Abraham Accords was stipulated in the text of the deal – which has not been released – or that Saudi Arabia had agreed to that condition, or would be forced to join the accords.
Meanwhile Israel welcomed Trump’s statement.
Posting on X, Prime Minister Benjamin Netanyahu’s office said Saudi Arabia joining the accords “would be an historic leap forward for peace in the Middle East”.
The statement did not mention the nuclear deal. However, Israeli Economy Minister Nir Barkat said previously his country “can manage it” if Saudi Arabia had nuclear power for peaceful means.
Israel itself is widely believed to have nuclear weapons, but it neither confirms nor denies that this is the case.
The US-Saudi deal, whose signing was announced on Wednesday, is described as a “peaceful nuclear co-operation agreement” that will provide “great access for American companies in the Saudi nuclear energy programme” by the US energy department.
The nuclear issue has been at the centre of the months-long US-Israeli conflict with Iran.
