Could Global Thermonuclear War Wipe Out Human Civilization?

[98jersey]

I have a question about nukes.

If all the nukes in the entire world were detonated at once and dispersed for maximum kill, we're talking China, Russia, Pakistan, USA, etc...
evertthing

Could we kill all the human civilazition, or if not, what percentage could we kill?

I'm having a debate with my brother. I'd say less than half, my brother says 75% or more , probably everyone.

99.9% probably.

The US and Russian and Chinese nuclear weapons stockpiles are enormous and their power is ungodly. 1 nuclear ballistic missile submarine can destroy probably somethign like 30% of the population of a continent probably (besides asia) and there's a few dozen of those in the seas. Plus of course we have our silos (US) and russia has its ICBM military forces which are a few thousand nuclear warheads each.

Then of course, count in the theoretical nuclear winter and that's pretty much it for all of mankind except in Australia... so lol, unless I am wrong, with the 'nuclera winter' theory being true, all but the survivors of the Australian attack would survive.

This is a difficult question to answer definitively as it ultimately depends on a variety of factors such as the number and strength of the nukes, the location of detonation, and the overall response and survival strategies of different countries. However, one thing is certain - a global thermonuclear war would have catastrophic consequences for humanity. The sheer destructive power of nuclear weapons is unimaginable and would likely result in widespread devastation and loss of life.

While it is impossible to predict with certainty, it is highly unlikely that a global thermonuclear war could result in the complete annihilation of human civilization. The human race has shown a remarkable ability to survive and rebuild in the face of disaster. Additionally, many countries have nuclear deterrence strategies in place that may prevent all-out nuclear war.

That being said, even a partial nuclear exchange would have devastating effects on the world population, infrastructure, and environment. The immediate effects of the explosions and radiation would cause mass casualties and destruction, while the long-term effects of nuclear fallout and nuclear winter would have a significant impact on the survival of the remaining population.

In conclusion, while it is difficult to determine the exact percentage of human civilization that could be killed in a global thermonuclear war, the consequences would be catastrophic and it is a scenario that should be avoided at all costs. Rather than debating the extent of potential destruction, it is important to focus on preventing such a devastating event from ever occurring.
