Should the US Navy move the fleet out of harm's way?

U.S. Navy is not in "harms way" to begin with.

I imagine that's exactly what a terrorist would like the US Navy to think, and I daresay the sailors on the USS Cole thought that five minutes before they were attacked.

No (modern) precident exists for terrorist attacks in domestic ports on naval assets in Western states AFAIK.

Well that's true, but it didn't stop the IRA blowing up Lord Louis Mountbatten's boat slap bang in the middle of when the UK was on high alert to specific threats from that organisation, killing him and Baroness Brabourne among others, and on the same day also killing eighteen soldiers from the Parachute Regiment at Warrenpoint. This, in the same year that the INLA also blew up MP Airey Neave's car on the ramp coming out of Parliament, killing him too. All these being just a small selection of the bombings which took place that year in the UK, despite security measures and awareness of threats.

When the US Air Force can forget about some nuclear weapons slung under an aircraft and leave it sitting unguarded on the apron at a base for hours before anyone thought something was amiss, it's not a stretch to imagine that the security at Naval bases might have a few gaps in it. Complacency concerning enemies and potential enemies is just asking for it.
