...not an explanation of military strategy. But apparently you failed to detect the difference.
The grip on reality is that our nation is wholly unable to open up a new "front" in the "war on terror." We currently have our hands full in Afghanistan and Iraq. We are hardly in a position to attack and convert Iran into the "democracy" we don't have in Iraq. And given our current status (or lack of it) among nations, we'd be hard put to conjure allies to help us take down Iran if we had to.
Meanwhile, North Korea is mulling over conducting a nuclear test.
Yup...George Bush and his sycophantic, pedophilac Republicans in Congress have made the world and teenage boys "safer." Not. These are your heroes Scott, not mine.
