Iran Testing The Water?

Iran has conceded to talks about its nuclear program, but has refused to stop the program while engaged in meaningless chit-chat with the U.N.

Are politicians so stupid that they cannot see a stall tactic for what it is, or is this flat-out corruption?

In response to Iran snubbing another U.N. deadline to stop uranium enrichment, the U.S. has sent another aircraft carrier to the Gulf and put sanctions on some Iranian banks and businesses.

And in a seeming response to increased U.S. military pressure, Iran has begun to "test" the waters near Iraqi offshore oil terminals.

Iranian ships have been crossing into Iraqi waters, but such activity has dramatically increased over the last week. U.S. officials believe that the Iranians are attempting to assess U.S. military response and operation practices, but "do not see the moves as aggressive or provocative."

Hell, why would they? We find Iranian bombs and munitions, and Iranian regular military firing on our soldiers, and they don't see that as an act of war!

This could all be posturing on the Iranian's part, but somehow I doubt it.
