The United States' preparation to strike Iran is complete with the top commander of the US Central Command having received computerised plans for Operation Iranian Freedom, a report has said.

'American military operations for a major conventional war with Iran extend far beyond targeting suspect weapons of mass destruction facilities and will enable President George Bush to destroy Iran's military, political and economic infrastructure overnight using conventional weapons,' the New Statesman magazine has said in a report.

In the report titled Attack - Revealed: America's plans to invade Iran, the journal quoting British military sources, said, 'The US military switched its whole focus to Iran' as soon as Saddam Hussein was removed from power. The White House continued this strategy, even though it had American forces bogged down in Iraq, the report said.

The US army, navy, air force and marines have all prepared battle plans and spent four years building bases and training for Operation Iranian Freedom, it said.

Admiral Fallon, the new head of US Central Command, has inherited computerised plans under the name TIRANT -- Theatre Iran Near Term. Even as the sending of a second aircraft carrier to the Gulf has been highlighted, the US navy can put six carriers into battle at a month's notice, the report added.
