WASHINGTON D.C.: White House national security adviser Jake Sullivan told his Israeli counterpart Eyal Hulata on Tuesday that President Joe Biden's administration believes diplomacy is the best way to make sure Iran never gets a nuclear weapon, the White House said.

Sullivan also noted at the White House meeting that Biden 鈥渉as made clear that if diplomacy fails, the United States is prepared to turn to other options,鈥� the White House said.

Hulata is on a visit to Washington, which US officials said will allow the two allies to share intelligence and develop a 鈥渂aseline assessment鈥� of how far Tehran's nuclear program has advanced.

Asked what actions were under consideration and whether that included military options, a US official said 鈥渨e'll be prepared to take measures that are necessary鈥� but did not elaborate.

The official said that Iran was 鈥渟ending indications to a number of parties that they are preparing to come back to Vienna,鈥� where the US and Iran held indirect talks earlier this year that stalled.
