Israel sent (I think two)submarines through the Suez Canal just before Bush left office. It was probably the last opportunity to do so. I haven’t read about them coming back, so I assume they’re being maintained by India and that they patrol the Persian Gulf. I’m fairly certain they can fire cruise missiles, but the only target they could really destroy would be Iran’s oil industry.
Also, Syria bought a top-of-the-line Russian anti aircraft system to protect their rebuilt nuclear plant. But the radars that control the missiles were on 3 Russian ships in the Gulf. If Israel is to conduct any serious bombing in Syria those ships would have to go.

Couldn’t they also hit Mecca and Medina?
Maybe they're in Aqaba?
The Israeli port of Ellat is on the Red Sea. No need to travel the Suez.
