Russia and Ukraine

[The Grand Nudger]

Some sources estimate that Russian death since the starting of this war could be as high as 800,000.

That's the total casualty list, only a portion of it are kias, half or more are wia.  The source is the ukranian mod, and open source intelligence analysis as well as western intelligence agencies agree that the estimate is sound.  Every now and again, some russian forgets their script, and we get a glimpse into the internal numbers and domestic propaganda of the russian war effort.  It's not great.  There are so many kia wia and mia that the mod can't both pay their now-reduced-by-90% benefits and the war bill.  There aren't enough care facilities in the country to treat the fraction of wounded they must just for pr purposes. 
 

North Korean “elite” troops are now being used in zombie waves (they drug the soldiers and send them to die on Ukrainian lines, wave after wave until they are able to takeover Ukrainian positions). The number of confirmed North Korean deaths is actually at 5000.
 
The Wagner Group alone is said to have lost 200,000 men just to take the city of Bakhmut.

It's not just the number.  They were russias best troops.  Their token professional forces had already been decimated in the opening stages of the invasion.  The north koreans are also, hilariously, the best troops currently in the russian army.
 

Why does anyone even think of using similar methods to invade a sovereign country?

So I don’t know if he is going to be able to solve of even improve anything on the ground, but Donald Trump is absolutely right in saying that this war shouldn’t have started in the first place

Information.  Russian commanders lie.  Russian troops do not follow orders.  In this environment, the only way to know for sure your orders have been followed is a meatwave.  You just count the dead and the inches.  Trumps never right about anything and he isn't right about that.  Russia has been invading ukraine since 2014.  They were invading ukraine thrughout his entire first presidency and he knew that, which is why he thought he could extort zelensky. 

If russian crimes on ukranian territory against ukranian people were ever to be stopped. If ukraine was ever to be a sovereign country. If international law is still commited to respecting sovreign borders..then the war was always going to happen, and should happen.  The only question that remains is which side a person or nation is on.
