“We call for an immediate ceasefire and the withdrawal of all Russian military forces from Ukraine, and for all possible efforts at dialogue to prevent this ultimate disaster.”

“We call on Russia and NATO to explicitly renounce any use of nuclear weapons in this conflict, and we call on all countries to support the Treaty on the Prohibition of Nuclear Weapons to ensure that we never again face a similar moment of nuclear danger.”

This would be making true headway in this world. Not wars. Dialogue and peacemaking on both sides. Otherwise, the big KABOOM and bye, bye humanity.
