Maybe it’s my lack of imagination, but I can’t imagine a dispute between those two nations that would be justified in any way at this time. Likewise, I can’t see how the relationship could degrade to point where war was the only feasible option.

World being configured as it is today, I don’t see a reason to point a gun at anybody, for any reason.

While we enjoy that luxury, it’s the perfect time to: talk with someone who you disagree with on a fundamental level. Get to know them as a fellow human being. Listen to their life experiences, & share your life experiences with them. Discuss deep questions openly and honestly. Don’t be afraid. Be honest, be sincere.
