Magnifica Humanitas §64

⁶⁴ This also applies to international politics. As the divide between nations widens, a mentality of confrontation and aggression begins to take hold, and the difficult path toward a more united and fraternal world suffers new and painful setbacks. In this context, speaking of a shared journey toward a more just development for the entire human family “sounds like madness.” Yet we must not lose hope. I invite everyone to conceive of ways of cooperating and of more effective international institutions, capable of safeguarding the global common good without compromising the legitimate diversity of peoples and nations. Indeed, the promotion of the common good can never be separated from respect for the right of peoples to exist, to preserve their own identity and to contribute their unique qualities to the family of nations. Moreover, any attempt or plan to eliminate or subjugate a nation is gravely immoral and therefore unacceptable.
