Supporters of the National Council of Resistance of Iran (NCRI) have claimed that the mullahs' nuclear advancement was a direct result of appeasement towards Iran by the West.
They rallied opposite the Foreign Office in London and called on the five permanent members of the UN Security Council and Germany to stand firm against the Iran regime and adopt a more forceful resolution imposing comprehensive sanctions including arms, technological, diplomatic and an oil embargo against them.
The Iranians delivered a petition to Foreign Secretary Margaret Beckett. They said: "The incentives and talking approach has been tried in the past many times and proved ineffective with this regime. Years of conciliatory approaches and negotiations gave the regime a chance to secretly develop its nuclear project.
"The mullahs' nuclear progress is the direct result of appeasement. The continuation of appeasement will inevitably lead to a war which will be imposed on the region and the world by the ruling clerics in Iran.
"The only way to deal with this global threat and to stop Iran from obtaining a nuclear bomb is decisiveness. There is no need for a war or for continuing the path of appeasement. There is a third viable option available. That is democratic change in Iran through Iranian people and their popular Resistance movement."
Earlier, Downing Street warned Iran against "continued flouting" of its United Nations obligations as senior diplomats from around the world gathered in London to discuss the next steps against the rogue nuclear nation.
Officials from the five permanent UN Security Council members - Britain, Russia, China, US and France - plus Germany met at the Foreign Office in London.
They discussed how to respond to Iran's failure to respect a UN deadline to halt its uranium enrichment work.
The UN's nuclear watchdog agency confirmed on Thursday that Iran had ignored an ultimatum by the Security Council to freeze enrichment - a possible pathway to nuclear arms - and had instead expanded its programme.
The Security Council adopted limited economic sanctions against Iran in December. Prime Minister Tony Blair's official spokesman said there was a desire "to go further".
