When US astronauts and Soviet cosmonauts first met in the space back in 70th it was great relief from permanent terror of nuclear war and giant leap toward the end of insane arm race. Now we have permanent ISS as assurance of global peace. Besides all science. Sure, we still have a lot to do on Earth, stopping wars and disparity of nations first of all, but that JFK's space decision was crucial in following peaceful defeat of Evil. Space exploration, as any exploration if fact, is great engine for overall human progress and establishment of global justice and peace.
