This is an amazing presentation.
So many people tend to view jurisdictional geography as if it were similar to physical geography, static or tectonic in movement.
And most Americans have difficulty even understanding our own county and North America's historical boundary ebb and flow, especially if we look at pre-1775.
So to attempt to understand the feelings of those in Europe, the middle east, Asia, or anywhere that is not our personal area of expertise when it comes to these often historically arbitrary boundaries is to do those peoples a disservice.
For example, I personally had little to no knowledge of the Balkans, and "former Yugoslavia" until I deployed there as part of Operation Joint Endeavor. Talking with those who lived there, and their perspective of our attempts to stabilize the region (Dayton Accords) was a real eye opener.
So for me, I find it difficult to offer an opinion of what is the appropriate action in regards to UA and RU, not having a full understanding of the "geographical" history, for lack of a better phrase.
