Civil Wars rarely result in outright victories. The American Civil War is the exception.
Ukraine - Western Ukraine, is simply outmatched and outgunned by the more populous east, which enjoys the support of Russia. It never stood a chance of regaining control over the entire country.
People are going to demand the army cut its losses and pull out of the Donbass. Those same West Ukie soldiers who won’t bleed there will defend their home turf.
Which Putin won’t take.
This is not a civil war, this is a Russian invasion
Most in the east don't want to leave Ukraine and don't want to be part of Russia.
Your above description excluding the part about Russian support is wrong.
That is complete crap.
There is no “civil war”. This is a 100% Russians engineered terrorist operation, which just evolved into a war of aggression against Ukraine. This is about as much a civil war as 9/11 was.
The US needs to give Ukraine massive military aide, there need to be mountains of dead Russian soldiers, and explosions going off all over Moscow and St. Petersburg. This a as clear cut case of good and evil as you will get in the 21st century, a people yearning to be free being devoured by power mad tyrant.
Death to Putin.
