Happy Veterans Day and Remembrance Day. Regardless of how bad and horrible war is, there is no denying war, especially World War 2 contributed greatly to the advancement of Science, Technology and Medicine. This is because the need to survive and win the war, all countries involved poured unlimited resources into science and technology to develop the best weapons to defeat their enemies, to find the best medicine (example penicillin during the Great War) for their soldiers.
For example, Nazi Germany gave us Jet Engine technology and Rockets, USA gave us Atomic Energy, United Kingdom gave us Radar and Computer. The Cold War gave us Satellite, Internet, GPS and many more. Not to mention advances in medicine because the country with the best medicine is more likely to save their soldiers and quickly redeploy them back into the battlefield.
There are always two sides to a coin. As the saying goes, there are no good guys or bad guys in a war, only winners and losers. As George Orwell puts it beautifully, “He who controls the past controls the future. He who controls the present controls the past.”
