Are we seeing the previews to OIF II (Operation Iranian Freedom)?

The drum beat to war is being sounded, louder and louder. However, is this the best course of action, especially considering we are bogged down in two conflicts? Not to mention the nagging questions posed by this would liberation; is this truly for the Iranian people, national security, or OIL? The question will be asked, America only seems to be interested in freedom or fighting terrorism when oil is involved, can America afford to be the enemy of the majority of the world? Lastly, will the world truly come to an end of Iran becomes a nuclear nation? Many nations have nuclear bombs, including the US and Israel, the world has not ended yet?
