One of the ships, the Hanit, already crossed the canal both ways in June, in what the source said was the first case of a large Israeli warship using the strategic waterway, although this was not possible to confirm officially.This (and last week's submarine transits) constitutes a warning to the various Islamofascist despots (the Saudis, the Syrians, the Iranians, various Shi'ite faces) that Egypt won't reprise the Nasserite attacks on Israeli ships which triggered three wars in less than twenty years.
I think the Sunni Arabs are giving tacit support to Israel against the Shi’ite Persians because of Arab fears of Persian hegemony.
When Israel takes out the Iranian nukes, they will be roundly condemned by Sunni Arabs (and the rest of the world). However, the Sunnis will also be smiling in relief.
