In a move that experts say could significantly hurt Israel’s military readiness, pilots and other personnel issued a warning after Benjamin Netanyahu pressed ahead with a plan to limit judicial power.

More than a thousand pilots and other personnel in the Israeli Air Force reserve said on Friday that they would stop reporting for duty if the government pushes through a contentious plan next week to reduce judicial power without broader consensus.

In a joint letter released Friday, 1,142 Air Force reservists — including 235 fighter pilots, 98 transport plane pilots, 89 helicopter pilots and 173 drone operators — said they would not serve if the government proceeded with its plan to reduce the ways in which the Supreme Court can overrule the government.
