This reminds me of a recent vote in the EU parlament where the No vote had to reach a certain value above 50% to carry the day. Even though the vote did end up with a No majority, it passed because the No vote didn't reach the required negativity!
Now that's true democracy.
If Icelanders don't want to join a democracy like that, negotiate until they do! After all, the politicians know what is best for the populace.
