In game theory, bluffing is absolutely necessary, whether with a losing or winning hand, in order to throw randomness in the game and scramble the tells.
I sure hope Israel bluffs, because any one at war should know how to bluff the enemy. IT is essential. However in this day and age of peace at any cost and nuclear disarmament bs, we are losing that asset.
In any case, Israel has played a bluffing card as far as having nukes and defending itself. It’s how the game is plaid in war, tactics and strategies.
If Israel is bluffing, then ISrael will attack Iran.
