There is no direct evidence that nuclear weapons prevented a world war. Conversely, it is known that they nearly caused one.
Sentiment: NEGATIVE
As for the assertion that nuclear weapons prevent wars, how many more wars are needed to refute this arguments? Tens of millions have died in the many wars that have taken place since 1945.
Nuclear weapons are infinitely less important in our foreign policy than they were in the days of the Cold War. I don't think we need nuclear weapons any longer.
It's a near miracle that nuclear war has so far been avoided.
The only thing that kept the Cold War cold was the mutual deterrence afforded by nuclear weapons.
Nuclear weapons continue to occupy a unique place in global security affairs. No other weapons, in my opinion, anyway, match their potential for prompt and long-term damage and their strategic impact.
The other countries did not share the same concern the United States had in the early '90's - that North Korea actually had an ongoing nuclear weapons program.
What has kept the world safe from the bomb since 1945 has not been deterrence, in the sense of fear of specific weapons, so much as it's been memory. The memory of what happened at Hiroshima.
A world without nuclear weapons would be less stable and more dangerous for all of us.
We won the Cold War because we showed nuclear vigilance and diligence.
Japan is the only country in the world which suffered from the scourge of nuclear weapons.
