How did WW2 change the world?

please mark me brainliest

The war accelerated technology and brought new methods for fighting and killing to the later wars. The air forces improved greatly, such as air transport, strategic bombing (to use bombs to destroy industry and morale), as well as radar, and weapons for destroying aircraft.

the labor movement in the united states grew out of the need to protect the common interest of workers

for those in the industrial sector organized labor unions fought for better wages reasonable hours and safer working conditions

  in the 19th century trade unionism was mainly a movement of skilled workers.
