The immediate effect of the collapse of the largest coalition in Israel's history - as well as one of the most short-lived - will be to leave the Netanyahu Government with a much narrower majority of 66 of the Knesset's 120 seats.
But Kadima's departure could well hasten elections, probably to next January or February, not least because of the difficulties of passing a Budget with a smaller majority in what would anyway be an election year.
But the move is unlikely to affect the Government's right-wing tenor towards the occupation, Israeli settlements, and the dormant peace process with the Palestinians, which remained largely unchanged despite hopes by the United States and Israel's other allies that it would be softened while Netanyahu had a broader coalition.
This was illustrated yesterday when the military-appointed Board of Education covering the West Bank approved a far-reaching recommendation, heavily backed by Netanyahu's Likud Education and Finance Ministers, to make the college in the settlement of Ariel into a fully fledged university despite the strong opposition of many academic leaders in Israel itself.
The effect on the electoral fortunes of the now-divorced coalition partners is less clear. Netanyahu remains a consistently popular Prime Minister, though he now risks losing at least some votes among a body of secular electors - including on the centre and right - for whom drafting the ultra-orthodox is a highly salient issue.
But the future for Kadima is likely to be much more dire. While Mofaz could pick up a handful of seats as a champion of drafting the ultra-orthodox, the polls suggested the party was in meltdown before it joined the coalition and there was widespread speculation yesterday that it could split or even disintegrate.
The exemptions for the ultra-orthodox from military service - and the benefits for those not working - date from the foundation of the state in 1948 when a few hundred were left to pursue their biblical studies to rebuild religious scholarship that had been wiped out by the Holocaust. Their numbers have now grown to about 60,000.
Opposing changes to the system, Rabbi Obadia Yosef, the hugely influential spiritual leader of the ultra-orthodox party Shas, whose chairman, Eli Yishai, is Netanyahu's Interior Minister, said on Sunday that without students at yeshivas - religious colleges - "the world would be destroyed". While acknowledging that the defence force "guards us", he added that "only the Torah" could protect Israel "from evil".
