The parties to the Vienna talks on Iran's nuclear program have returned to their capitals and are expected to reconvene soon for a final round.

The nuclear negotiations in Vienna continue. The Iranians are setting the tone and pace while the Americans struggle to keep alive the possibility of a deal.

The original objective of the JCPOA—to keep Iran one year from "breakout" to one-bomb's worth of weapons-grade uranium—is long gone.

It will be in both countries' best interest if Bennett tells Biden privately—but directly—what the latter's administration is doing wrong.

The Iranian strategy in Vienna is obvious: wield the threat of nuclear escalation to extort tens of billions of dollars in sanctions relief and win tacit permission to forge ahead on nuclear R&D.

Any new deal must address all three elements of Tehran's illicit nuclear program: fissile materials, weaponization and the means of delivery.

Nuclear cooperation between the U.S., Israel, the UAE and Saudi Arabia could help prevent a cascade of Middle Eastern nuclear proliferation.

The next two months are absolutely critical.

Given recent events, Israel must commit to decoupling from China.
