You know the funny thing about this situation is Bush's policies were really the catalyst towards Iran getting nukes. After he came into power and started promoting his nutty democratic domination theory, the Iranian hardliners rose to power in the face of western threats. Iraq, under Saddam, has kept Iran in cheque very well, obvious foes shown by the Ira
Iran war, but what does Bush do? He invades Iraq and gets rid of Saddam, getting rid of an obstacle and threat for Iran. Ultimately giving them more freedom to pursue nukes. Not only this, but the current Iraqi government has good relations, far better than Saddam, with Iran, so America essentially eliminated a key regional figure who could cheque Iranian power. Now the Iranian hardliners are in power and pursuing/ probably already have, enriched uranium.
Ironic don't you think?
