After months of reluctance, Israel is softening its opposition to providing military aid to Ukraine, as Iran’s deepening support for Russia’s invasion evolves into a threat to Israeli security.

A turning point came late last month, when Israeli Defense Minister Benny Gantz took a long-requested call from his Ukrainian counterpart Oleksii Reznikov. Israel committed to help Ukraine develop an early-warning system, similar to one that alerts Israelis to incoming fire from the Gaza Strip.

Gantz also agreed to assess Ukraine’s air-defense alert needs, though Israel is declining to provide Ukraine the means to shoot down incoming drones and missiles.
