Israel’s Supreme Court on Tuesday ruled unanimously that the military must begin drafting ultra-Orthodox men for military service, a decision that could lead to the collapse of Prime Minister Benjamin Netanyahu’s governing coalition as Israel continues to wage war in Gaza.

The court ruled that in the absence of a law that distinguishes between Jewish seminary students and other draftees, Israel’s compulsory military service system applies to the ultra-Orthodox like any other citizens.

Under longstanding arrangements, ultra-Orthodox men have been exempt from the draft, which is compulsory for most Jewish men and women. These exemptions have long been a source of anger among the secular public, a divide that has widened during the eight-month-old war, as the military has called up tens of thousands of soldiers and says it needs all the manpower it can get. Over 600 soldiers have been killed.
