There will never be a nuclear war.
I always said this.
Once a country makes a decision to use nuclear weapons on a other country
It also needs to accept the fact, that there own country and population will experience the same nuclear attacks.
Same goes with Putin, Macron or Trump or anybody...
If Trump wants to nuke Moscow. You can be pretty sure New York or other high value targets will be targeted by Russia.
Causing lots of civilian casualties (millions) and nuclear fall out for years on both sides.
I'm not talking about who will take out most of the incoming missiles, and who will cause most damage.
A nuclear war will cause millions of deaths on both sides. And the world leaders know this for damn sure. There will be future wars. But no nation will launch nuclear missiles. Thats why i don't take these political statements for real... When one nuclear missiles is gonna be launched. Our planet is screwed.
The first country who will actually launch nuclear missiles, will create a global shock and condemnation from the entire world. Basically every nation will use all there military force on that guilty nation. That nation will be in ruins and their nuclear armament is seized. Then the world will sign treaties so such things can never happen again. (if the world isn't already completly destroyed

)
