"The US and its sympathizers in Iran's nuclear issue should wait and see the next initiative of the Iranian nation, and they will soon realize that they have made a mistake (by imposing new sanctions on Iran)," Vice-President and Head of the National Youth Organization Mehrdad Bazrpash told FNA on Saturday.
"And those countries which do not support Iran's righteous stances will also understand that they have made a mistake similar to the past," Bazrpash added.
He underlined that Iran's nuclear program is irreversible and Ahmadinejad's administration will not retreat from the country's nuclear stance.
"This (nuclear program) is a decision of the ruling system and is not a decision by an individual or (political) faction," he reiterated.
The vice-president for youths affairs further pointed out that approval of a new resolution at the UN Security Council showed that the council has been the most undemocratic international body all throughout the history, "because three countries want to impose their will on the other countries and they decide instead of other states".
The US-proposed resolution was passed with 12 votes in favor, two against and one abstention.
Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program, while they have never presented any corroborative evidence to substantiate their allegations. Iran denies the charges and insists that its nuclear program is for peaceful purposes only.
Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry.
Despite the rules enshrined in the Non-Proliferation Treaty (NPT) entitling every member state, including Iran, to the right of uranium enrichment, Tehran is now under four rounds of UN Security Council sanctions for turning down West's calls to give up its right of uranium enrichment.
Tehran has dismissed West's demands as politically tainted and illogical, stressing that sanctions and pressures merely consolidate Iranians' national resolve to continue the path.
