Has the US Finally Come to It's Senses?

Al-Jazeera reported today that the US and UK are urging Israel not to strike Iran. Is this a sign of the US backing down, or is it simply an act of throwing the ball back in Iran's court, forcing them to make the next move towards "peace" or war? I'm sure we'll see in the next week when STRATFOR releases it's report on the location of US carriers.
