What happens when a strong nation needs what a weak nation has?
Ukraine looked weak, and they had what Putin wanted. So, he chose to invade.
What was it that Ukraine had, that Putin wanted?
The second largest natural gas reserves in Europe. The sixth largest coal reserves in the world. Plenty of oil.
Russia wants what Ukraine has, so they went to war to get it. Unfortunately, this will not be the last energy war.
The ride of the Red Horse, was never going to be very fun.
