When change occurs, sometimes it's a big one:

UNITED NATIONS (Reuters) - Allowing Iran to acquire nuclear weapons could destabilize the world and lead to war, French President Nicolas Sarkozy told the United Nations on Tuesday.

In his maiden speech to the U.N. General Assembly, Sarkozy said: "There will be no peace in the world if the international community falters in the face of nuclear arms proliferation."

Iran was entitled to nuclear power for civilian purposes, he said, "but if we allow Iran to acquire nuclear weapons, we would incur an unacceptable risk to stability in the region and in the world".

In a broader warning against the dangers of appeasement, the new French leader said: "Weakness and renunciation do not lead to peace. They lead to war."
