I'd say we're both arguing the 'ought in this situation from practicality, and wanting to avoid destruction.
But is it practical to assume good will of other people?
If such were true, armies would be disbanded, police would not be needed.
Evil people, evil intent, they both exist.
Ambition, greed, disregard for others.
Pacifism is a noble goal, but misguided.
It is why nations exist, because of mans twisted nature. The fairer versions that exist now, came into being by better men's realization of this. That if they did not steel their hearts and form nations for defense themselves, they would be overtaken by bands of bandits and crowds of criminals.
Necessary evil, is a right.
Something that people 'should go about, for the sake of practicality.
In America, the right for all citizens to own a gun is accepted.
Simply because there are exceptions to a rule, such as criminals and mental deficients, does not 'break the statement that owning a gun is the right of an American.
And so I return to my argument on the rights of nations to nuclear weapons.
So long as significant differences exist, so too shall exist conflict.
There's no denying conflict, which exists to the farthest reaches of mankind's history.
To expect countries to to lay down the greatest weapon they can achieve, to leave themselves defenseless, is folly.
For nations have always had their secret ways and preparations, it would be an agreement in name only.
Better to go with the statement all nations have a right to nuclear arms, but then clarify the statement.
Nations that are regarded as stable, powerful, well run enough to afford to equip themselves.
Weaker nations, have their policies, aims, even government selected by the more powerful nations. Into who's realm of influence these weaker nations fall.
Can they 'truly be considered nations then, if they fall under the influence of greater nations?
I say no.
Better instead that their position be recognized. They have no rights to nuclear weapons, because they are not sovereign nations. Not if they are controlled by more powerful nations.
It was Britain's folly to let their Empire slip away, and it was the folly of the Allies after WW2, to not capitalize on their military advantage in the world.
Instead they have allowed cultures and peoples of different values of themselves to assert themselves, to push 'their values upon the people of countries which once held the world in their hands.
It is the mistaking this world for one of peace, rather than conflict, which has eroded the first worlds hegemony.
Conflict 'will come, for as I said in round 1,
It was only the limitations of travel and communication, that limited the Empires of old.
