Definitely powerful words from John F Kennedy. A total war with nuclear weapons is unthinkable and would mean the end of mankind. Hopefully it never gets to that. All we need are prudent leaders ready to embrace dialogue and diplomacy. everything should be done to avert wars and end the current ones.
That would end so much death and suffering that is going on in places like Gaza and Ukraine.
Looking forward to a peaceful world where human beings can thrive and reach their full potential. Am sure we will see a peaceful world in our lifetime, fingers crossed :}
