“Nuclear-weapon states should negotiate and conclude a treaty on no-first-use of nuclear weapons against each other or make a political statement in this regard,” Sun said.
China and India are currently the only two nuclear powers to formally maintain a no first use policy. Russia and the United States have the world’s biggest nuclear arsenals.
Last I remember, USA was the only country to have abused nukes against Japan, and later USA and UK sent nuclear ships to nuke India (Russia helped save us from those white devils). USA also supplied banned clusterbombs to NATO proxy Ukraine, which they used against Russia. Russia neither used nukes nor banned weapons.
