Nukes during the Cold War worked as a deterrent for USSR and USA.
But today if nukes fall in the hands of Iran, well, that wil be another more dangerous story!
Not even close.
We negotiated with the Soviet Union who had 5,000 thermo-nuclear weapons already targeted at our major cities for decades that were on the tip of intercontinental ballistic missiles that could reach anywhere on Earth.
Iran will never be a threat to the U.S. If anyone attacks Israel and it looks like Israel won't be able to handle it we'd have a hundred thousand troops there in a week.
The threat of ANY new country getting an 'atomic' weapon is troublesome simply because the more there are the more likely one will find its way into the wrong hands. But if any nation on Earth is willing to sell these weapons to the wrong people it is the North Koreans and even they understand that if such a weapon were used against the U.S. we wouldn't hesitate to wreak destruction on them, regardless of what China said.
And we need to clarify between atomic weapons and thermo-nuclear weapons.
Atomic weapons, like the two dropped on Japan during WW2, had a yield between 10-20 kilotons. Or 10,000 to 20,000 tons of TNT. An average thermo-nuclear bomb has a yield of 3,500 kilotons or 3,500,000 tons of TNT. 1000 times the destructive power of an atomic weapon.
The bombs North Korea tested were 2-12 kilotons. Atomic weapons. Technology to go to a thermo-nuclear device is far more complex and they likely won't reach that stage for a very long time. The same if Iran ever achieved an atomic weapon. Atomic weapons are bad enough but perspective is what is needed.
How cowardly the Republicans look to the rest of the world as they are terrified of a tiny country that has no atomic (let alone nuclear) weapons or missiles to deliver them. The same country that stared down the Soviet Union who had enough thermo-nuclear weapons to irradiate all of North America for the next 25,000 years so nothing could live here.
WTF has happened to Republicans. They have turned into a party of cowards.
