Inter-national wars are fought with technology, so this makes sense. However, I believe from an optimist perspective that ideas of global citizenship and environmental awareness / macro humanism are already in the post-formative, snowballing stages of disrupting nationalism, and without an anachronistic national affinity amongst the citizenry, countries are objectively becoming obsolete.

Wireless broadcast media, PSTN, air travel, international post, international financial networks, global supply chains, the internet have all contributed to this, but AI will drive it home: AI governance in particular. Once one nation adopts it, the benefits will be obvious and expand rapidly. Few yet realize how transformative the changes will be.
