Strategypage notes this:
The head of the Israeli military pointed out that Israel could carry out an attack on Iranian missile and nuclear weapons targets without help from any other nation (like the United States.)
Israel has had a lot of time to work out how they might hit Iran. If Israel is creative enough, I've suspected Israel could put together a strike option that Israel believes will work well enough.
UPDATE: More here. One can never tell if such a statement is real or bluff. But Israel has had a long time to create the capabilities to strike.
