Yes yes, we colonized America and genocided the natives. No one is arguing otherwise.
And most of our advances in rocketry came from Operation Paperclip. From ICBMs to the moon landing, we have Nazi scientists to thank.
But what about computers? The postwar generations used their wealth to fund pure science (something we deeply neglect today). It was very costly and took decades, but we invented microtransistors, the internet, wifi, GPS, etc. Every major technology that powers the computer you are using now was funded by hardworking Americans tax dollars.
And I'm not sure what Israel has to do with this, but yes they are following the "war on terror" model that America pioneered. Bomb civilians, label all the victims as terrorists, turn a blind eye to the consequences, and act surprised when your victims desire revenge.
