You can win a nuclear war
Efficient strategy :
Step 1 Gather Intel on Enemy
Step 2 Find out how has the launch codes & capability to issue the order for nuclear strikes
Step 3 Find out how will "push the buttons" to launch nukes
Step 4 Issue order for attack when your enemy is weak
Step 5 Simultaneous stealth attack: Divers will attack/sabotage anything that moves under and on the sea / Paratroopers/Assassins/Special Forces will attack the "Order Givers" ,they will also cut of communications and attack ground targets and anything that can fly
Step 6 Occupation and Psychological Warfare
Step 7 Population Assimilation or Population Annihilation
Step 8 Mission Accomplished New Territory Gained
You watch too many movies, and what happens in SF movies doesn't usually happen in reality. Your strategy means that a country, take China as an example - would be able to sabotage all of another country's nuclear facilities - take the USA as an example, and then destroy that country with nuclear weapons. So who or what will then occupy or wage war psychologically if everything is destroyed and unsuitable for life for the next 50 or 100 years?
Your tactics are full of holes and make no sense at all, and only war what can happen to you is the one in your head. Pause for a moment and ask yourself why are you writing such nonsense?
It's not movies ... it's a real life scenario ... if was China this was the perfect scenario for me as i have the largest population in the world ...with this scenario China can conquer USA without even launching nukes...i think only China can pull this off ...
The attack must be a surprise/stealth attack....enemy must not know what even hit him ...
