Smaller parties have gotten plenty in Israel, sometimes to the point that supporters of the larger parties feel they have less voice than whichever small party holds the balance of power at that moment.

Or, as in the current situation, there is simply no agreement, and they go months without a government. It's not clear that an inability to call re-elections would improve Israel's situation; they could be stuck for years with no government.

I agree, calling for "new elections" is a cop-out

Have an elected parliament sit for at least two years, maybe four, will go some way in making them work out their differences.
