Military strike on Iran and/or Syria imminent?

This morning, there was news of a US nuclear powered submarine colliding with a Japanese oiltanker in the Straits of Hormuz. It suggests that the narrow waterway right next to Iran is getting incredibly crowded.

Bush had recently replaced the two most senior generals overseeing the Iraq war, and according to this article from The Nation, it is an ominous sign, and I quote

"The choice of Fallon to replace Abizaid was highly unusual ...

Fallon is a Navy man, with experience in carrier operations, while most of Centcom's day-to-day work is on the ground, in the struggle against insurgents and warlords in Iraq and Afghanistan...

Fallon began his combat career as a Navy combat flyer in Vietnam, and he served with carrier-based forces for twenty-four years after that. He commanded a carrier battle wing during the first Gulf War in 1991 and led the naval group supporting NATO operations during the Bosnia conflict four years later.

...he is primed to oversee an air, missile and naval attack on Iran, should the President give the green light for such an assault--and the fact that Fallon has been moved from Pacom to Centcom means that such a move is very much on Bush's mind."

Ominous signs.
