> Bilaterals is a treaty, not a diktat.

The "diktat" is the thing you just voted on which says "we will not negotiate". There is always room for negotiation until you vote for a law that says "no negotiations, we are now legally mandated to do X".

> 2 years provides time for another referendum.

Voting for a no-negotiations amendment to your constitution as a negotiation tactic with the idea that you will later pass another constitutional amendment in a small window of time to revoke it is some kind of 4D checkers strategising that I suppose I am not enlightened enough to grasp.
