President Bush has warned on Wednesday that if Iran continues its nuclear program and manages to reach its goal of building nuclear weapons, a "World War Three" could break out taking in consideration the determination of the Islamic states to destroy Israel.

Iran’s president, Mahmoud Ahmadinejad, replied by asserting that Bush’s warning is nothing more than a "psychological war," Tehran media reported Thursday.

"This kind of remarks just reflects US anger over Iran's success in the international scenery and are nothing more than psychological war against Iran," the deputy head of the National Security Council, Rahman Fazli, told ISNA news agency.

According to Fazli’s sayings, Iran’s nuclear programs were approved by the International Atomic Energy Agency (IAEA). The five United Nations Security Council member states plus Germany also backed up the agreement between Iran and the IAEA as the basis for settling the nuclear dispute.

President Putin’s recent visit to Tehran was another issue that angered the United States as, according to Fazli’s statement, the Russian President’s visit has weakened US’s status in the Middle East.

Bush’s statement regarding Iran follows a series of events which saw Ahmadinejad declaring that, despite the difficulties encountered on its road to a nuclear based energy industry, the country he presides can’t be stopped from reaching its goal.

After about a week, Iran’s neighbors plus Russia have attended the Caspian Sea summit and signed a declaration which stipulates that they will not allow the US or its allies to use their territory for launching an attack on Iran.

America is currently making efforts to tighten international sanctions against the Islamic Republic over its uranium enrichment. According to the Bush administration, the uranium enrichment is just a cover used by the Iranian to hide their real intentions of building weapons of mass destruction.

Iran has firmly denied that claim.

Russia, which holds a veto in the United Nations Security Council, is currently building an atomic power plant in southwest Iran and underlined the fact that there's no evidence the Middle Eastern country is attempting to build an atomic bomb.
