North Korea's manpower is half the size of United States manpower. The United States has a population that has 120 million people fit for service. That means almost 40% of The United States population (316 million) could serve in the army. 1.4 million people are currently active personal and additional 850,000 are in the reserve.
However, if both sides were to account for their reserve personnel, North Korea would have a manpower that is 2.5 bigger than the US.
But manpower is just the tip of both countries armies. The main weapons to consider are the land units. North Korea has 1600 Self-Propelled Guns, 3,500 Towed Artillery, and 700 Multiple-Launch Rocket Systems while the US has SPG 1,934, Towed-Artillery: 1,791, MLRSs: 1,330.
In the air, United States beats North Korea without a doubt. NK has only 940 aircrafts compared to the US's 13,700. The most popular one that the Americans use is f-16 Fighting Falcon. The F-16 was developed in the states.
In the sea, United States loses 2:1. But only in numbers. The US has the strongest Navel Power: 10 Aircraft Carriers, 15 Frigates, 62 Destroyers, 72 Submarines, 13 Coastal Defense Crafts, and 13 Mine Warfares.
At the end of the day, United States could end this war in a blink. The US has over 5000 Nuclear Warheads. If it wanted, it could destroy the whole world. It's 'enemy' in this case has 0 confirmed warheads that could reach the coast of North America.
And let's say that the war did start and the US decided to not use the atomic bomb, they would still win since they have their own oil reserves. The opposition has to rely on imported oil and the US could have easily disrupted these trades.
So who do you think would win this war? Do you think North Korea has a chance or do you think it would have been destroyed by The United States? Let me know in the comments and if you think our assessment is wrong, don't hesitate to point out how!
