All quotes from Albert Einstein’s

The development of technology and of the implements of war says all about something akin to a shrinking of our planet. Economic interlinking has made the destinies of nations interdependent to a degree far greater than in previous years.

A permanent peace cannot be prepared by threats, but only by the honest attempt to create mutual trust. One should think that the wish to create a decent form of life on this planet and to avert the danger of unspeakable destruction would tame the passions of responsible men. You cannot rely on that, my young friends. May you succeed in activating the young generation in this sense, so that it will strive for a policy of peace on a grand scale. Thus you can not only defend yourself successfully, but you can serve your country and your descendants in a degree as was not given to any previous generation.

Before anything else, the young generation must become clear in its own mind. That minimal condition must be met in order to stop reciprocal military threat of one nation by any other nation or combinations of nations in the future.
