We used to see small border conflicts and border changes in a few third world countries, but the 2000s brought major border conflicts, leaving behind 50 years of ultra-peace. Structures such as the European Union aim to create a solid union structure to prevent such major border changes, but we can see that this has failed in areas outside their sphere of influence, such as 2014-Ukraine, Georgia and today Ukraine.
We are witnessing an interesting historical era, I wonder what time will show us.
