Via Raw Story, some horrible news if true - since an Israeli attack on Iran means they're seen in the Middle East as our surrogate. The Associated Press is still trying to confirm:

As unconfirmed reports of an imminent Israeli strike on Iran's nuclear facilities pick up steam in the Middle Eastern media, a US-based strategic intelligence company has released a chart showing US naval carriers massing near Iranian waters.

The chart, published by Stratfor and obtained by the Zero Hedge financial blog, shows that over the last few weeks a naval carrier -- the USS Harry S Truman -- has been positioned in the north Indian Ocean, not far from the Strait of Hormuz, which leads into the Persian Gulf. The carrier joins the USS Dwight D. Eisenhower, which was already located in the area. The chart is dated June 23, 2010.

Reports of mass movements of Israeli and US naval warships have been circulating through the media for weeks. On June 19, the Israeli newspaper Ha'aretz reported that 12 US and Israeli warships were seen moving through the Suez Canal from the Mediterranean Sea to the Red Sea.
