Israel is writing up options for a strike on nuclear facilities in Iran.
The Jerusalem Post reports that the Israeli Defense Force says that coordinating those plans with other countries is better.
But for now, Israel is preparing without assistance from the United States. One Israeli official says there's no need to rush into an operation right now.
However, last week Iran announced that it's now operating more than 5,000 centrifuges at its nuclear power plant and will continue with technological advances.
They have dismissed any possible Israeli strike and say Israel is making threats for its "psychological and media warfare."
