Israel is a unicameral parliament. So a ruling majority gets to do whatever it wants until the next election must be held or members of the ruling coalition defect and join the opposition on a vote of no confidence and the body dissolves. The Yisrael Beiteinu party was part of Bibi’s coalition but defected triggering the several elections in the past year or two.
Seems like there could be a lot of elections under a system like this.
