In WW2 we had to attack the Nazi first after Japanese invaded Pearl Harbour. The Nazis were getting too high tech. I mean look at the size of that
tank. We don't want to see hundreds of those invading the world.
Wonder how US got it's first jets in the cold war? This robot came from space and landed on the US airstrip so the airforce can copy its
technology.
This actually did happen in real life in the 90's. But, we won the war. How do we still have cities today? US let the Chinese over to rebuild
everything and scrap those crashed motherships. I mean look how fast China is building today.
Ever wonder why California is kind of messed up? This actually happened in 2011. The state is still trying to recover. As usual, US let the Chinese
rebuild most cities.
The reason why we don't remember any of these is because the gov has these devices because aliens gave it to us.
