Feinstein: Netanyahu Should 'Contain Himself'

"He has put out no real alternative."

On CNN's State of the Union Sunday, Sen. Dianne Feinstein advised Israeli Prime Minister Benjamin Netanyahu to "contain himself" when speaking against the Iranian nuclear deal.Otherwise, there could be consequences.

Host Jim Acosta asked the senator if she feels that Netanyahu is overstepping his bounds by trying to scuttle the deal. Feinstein responded:

Well, I think he's said what he's had to say. And to be candid with you, this can back backfire on him. And I wish that he would contain himself because he has put out no real alternative. In his speech to the Congress, no real alternative. Since then, no real alternative.

Netanyahu opened Sunday's program saying he feels heavier sanctions would be a better alternative, but when Feinstein was reminded that he did offer an alternative, she laughed:

Well, what -- it depends on what you believe more sanctions is going to do. More sanctions will certainly drive the program more underground, make it more difficult. I mean, a couple of years now have gone in to get this far.

Feinstein spoke candidly saying she finds this agreement "practical" and "better [than] it was ever going to be."

"It can signal a new day," Feinstein said. "Otherwise, we keep this dynamic going, which is not productive of anything that's positive for the region."
