I hate war as only a soldier who has lived it can, only as one who has seen its brutality, its futility, its stupidity.Dwight D. Eisenhower
If men can develop weapons that are so terrifying as to make the thought of global war include almost a sentence for suicide, you would think that man's intelligence and his comprehension... would include also his ability to find a peaceful solution.Dwight D. Eisenhower
The most terrible job in warfare is to be a second lieutenant leading a platoon when you are on the battlefield.Dwight D. Eisenhower
If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.Neil deGrasse Tyson
I don't want to be the embarrassment of the galaxy to have had the power to deflect an asteroid, and then not and end up going extinct. We'd be the laughingstock of the aliens of the cosmos if that were the case.Neil deGrasse Tyson
If you get asteroids about a kilometer in size, those are large enough and carry enough energy into our system to disrupt transportation, communication, the food chains, and that can be a really bad day on Earth.Neil deGrasse Tyson
Mars once was wet and fertile. It's now bone dry. Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.Neil deGrasse Tyson
