mistake of war
When a land grab is initiated and resistance is encountered you have war. If the invader prevails after much death, things will continue to be bad. Gorilla Warfare anyone? Remember dear Russia and its experiences in Afghanistan. The cost alone is prohibitive. Yet Putin can't back down because he'll be perceived for what he truly is. Talk about a no-win situation. Think about the military intelligence and the Emperor with no clothing. Oh how awful it would be to discover you are the ultimate 'International Pariah'. Time waits for nobody and the tick-toking toward consequences has commenced.
