The fact of the matter is that it is no one’s business but the countries involved. Ukraine tried to pull a fast one (with US encouragement) and they bit it. Too bad. They didn’t deserve to have Crimea (it is astounding how bad the infrastructure, etc. was before Russia took over).
“The fact of the matter is that it is no one’s business but the countries involved.”
A more accurate assessment would be to say that it is only Ukraine’s business. None of Russia’s business.
They did it for geopolitical reasons and the military aspect of Crimea. I think it is foolish and Crimean naval unite could easily be bottled up and destroyed in detail.
