Israeli leaders say the nation will respond to Iran’s weekend attack, but what that response will entail remains unclear.

“I can see a number of scenarios in which this does escalate to a regional and potentially even a global conflict,” says a former member of the National Security Council, Robert Greenway, adding, “I can see fewer ways in which we prevent that from occurring.”

Over the weekend, Iran launched about 300 drones and missiles at Israel. Unlike other attacks, this was not carried out by proxy terrorist groups in the region, but the nation of Iran itself.

If a larger conflict in the Middle East is to be avoided, says Greenway, who also serves as director of the Center for National Defense at The Heritage Foundation, the U.S. will need “to radically alter its policy and approach toward Iran and Israel.” (The Daily Signal is the news outlet of The Heritage Foundation.)

U.S. policy changes toward Iran should include “to deny it the resources necessary, and to restore deterrence, with the support of Israel and our partners and allies,” Greenway says.

Greenway joins “The Daily Signal Podcast” to explain what options Israel has as it considered retaliation against Iran, and how U.S. Middle East foreign policy is affecting the conflict.
