"Obama would never have uttered such cheap remarks if he had not suffered a major weakness and had not faced the (present) all-around dead-end in dealing with Iran," Deputy Head of the General Staff of Iran's Armed Forces Brigadier General Massoud Jazayeri said.
"The US is in a weak position and Obama's remarks on the use of nuclear weapons (against Iran and North Korea) are viewed as ultimate inability of an administration," Jazayeri stressed.
He called on all independent states, NGOs that support peace and justice, anti-war groups, intellectuals and all those who pursue a world free from war and American brutalities to take action against the United States' hegemonic policies and measures.
Earlier on Sunday, Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei reiterated that the recent remarks by US President Barack Obama in which he threatened to use nuclear weapons against Iran showed the true nature of the policies pursued by Washington.
"This statement is very strange and the world should not neglect it because the head of a state poses the threat of an atomic attack (against another state) in the 21st century which is the century of claims about support for human rights and campaign against terrorism," Ayatollah Khamenei said, addressing a number of senior military commanders from the Army and the Islamic Revolution Guards Corps (IRGC).
The United States pledged never to use nuclear weapons against the states that comply with the Non-Proliferation Treaties (NPT) as part of a much-anticipated review of nuclear arms strategy released Tuesday.
But the new pledge leaves open a nuclear strike against countries that have signed on to a global NPT but stand accused of violating its terms.
Obama, in an interview with the New York Times, said outright that the loophole would apply to "outliers like Iran and North Korea" that the US believes are developing nuclear weapons.
In response, Iranian President Mahmoud Ahmadinejad on Wednesday lashed out at Obama for his threatening remarks against Iran, and said Obama's comments indicated his lack of experience.
