The Biden administration is urging Arab nations to team up with Israel to counter Iranian missiles, but continued mistrust and technological differences mean any kind of alliance could be years away.

Officials and experts say a more realistic goal would be for Israel to share some intelligence with Arab states, conduct tabletop exercises together and perhaps even purchase additional compatible weaponry. That’s more attainable than a regional defense shield linking shooters with radars, satellites and other sensors, they say.

“It’s hard enough to get the U.S. Army and U.S. Navy sensors and effectors into a common command-and-control system,” said Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies. “It’s even more challenging when you have them coming from multiple countries in multiple languages.”
