Stupid political arguments of our time

John McCain says it is 'Time To 'Pull The Trigger' On Tougher Iran Sanctions' [TPM LiveWire].

There is just one teensy little problem. The US already has a full economic embargo on Iran. It is illegal for any US citizen to engage in any form of commerce with Iran including buying Iranian made goods and selling goods to Iran. So when McCain is saying that the US should pull the trigger, he is referring to a gun that has already been fired.

The only way that the US can bring any greater pressure to bear on Iran is by getting other countries to support the sanctions regime. And that in turn is made rather difficult by the fact that US credibility is rather poor after the lies told by Obama's predecessor to gain support for the US invasion of Iraq.
