Iraq has the world's second largest oil reserves which remain largely unexplored. The US invasion of Iraq has given Western oil companies access to Iraq's oil wealth through a new law establishing 30-year contracts allowing large scale exploitation of Iraqi oil fields. Critics argue the Iraq war was fought for control of Iraqi oil, especially with statements by Dick Cheney and the profits already accrued by companies with ties to the Bush administration through Iraq-related contracts and investments. The new Iraqi oil law means victory for Bush and the Western economic and political interests he represents in gaining long-term control and profits from Iraqi oil.
