Zionist deputy foreign minister said Thursday that a North Korean pledge to suspend nuclear tests in exchange for US aid should not be seen as a model for dealing with Iran's nuclear ambitions.

"The two cases are completely dissimilar," Danny Ayalon told Israeli public radio, hours before Zionist Prime Minister Benjamin Netanyahu was due to leave for talks in Washington with US President Barack Obama.

"We should congratulate United States foreign policy... but we have to remember that what has happened in North Korea is too little too late," Ayalon added. "They have already crossed the threshold of nuclear capability and that's certainly not what we would want to see happen in Iran."

White House spokesman Jay Carney warned on Wednesday that any military action against Iran would create "greater instability" that could threaten the safety of Americans in Afghanistan and Iraq.

Iran denies it is seeking nuclear weapons, but the ‘Israeli’ entity -- the Middle East's sole nuclear power -- has called for tough sanctions against Tehran to force it to abandon its peaceful nuclear activities.

“Iran's nuclear program will be the main topic of discussion when Obama and Netanyahu meet at the White House on Monday,” according to the Israeli premier.

Benjamin Netanyahu will fly overnight on Thursday to Canada, where he will meet Prime Minister Stephen Harper, before travelling to Washington for his first trip to the United States since he met Obama in September.
