There was no need for that rather arrogant sarcasm, Chris!
Could you have made a comment like Fred's in a language other than your own?
In the meantime, Fred, I knew what you meant!
Whether or not the Iranian ships actually do transit the canal into the Med, the crazy Iranian regime has already achieved a massive 'wind-up' of both the Israelis and the Yanks, simply by intimating that they want to come through (for the first time since the Ayatollah came to power).
They are perfectly legally entitled to do so providing they give the required notice and, unless there is a state of war, Egypt cannot stop them.
