I was reading another article where France24 back in Nov were saying that Israel would not attack Iran, that basically what with the world situation and all they already have a balance of terror situation and neither would want to take the first move.
This looks possibly and from your comment like playing the game of 'chicken' with Iran. A very risky ploy indeed.
Sailing in international waters is now 'playing chicken'? Well, I guess it is if your world viewpoint is that any time some pissant little dictator threatens you, you simply meekly retreat.
