Iran, Israel, and America on the Brink?

It's summertime and we want the livin' to be easy, but it's a tangle out there - on the economy and, potentially, on yet another warfront: war with Iran.

In recent weeks, the signals are hot - and all over the place. Israeli war games. Iranian missile tests. Blistering rhetoric and calls for cool.

U.S. and Israeli generals shuttling back and for the between Washington and Tel Aviv. Reporting that US special forces are already inside Iran.

That war could come before Bush leaves office. And today that a top US envoy will talk with Iran.
