Ukraine says it was attacked from Russia, Belarus, and the Crimea.

Many major cities have been attacked. It is clear that though Putin sent "peacekeepers" using Luhansk and Donetsk as a pretext, their mission has no particular relation to those insurrections or to the provinces they are in.

Putin said he intends to "demilitarize and denazify" Ukraine. Translated through his propaganda system, I think that means he threatens to remove the current "Nazi" government of Ukraine (never mind that it's led by a Jew) and impose a puppet government. Perhaps with permanent Russian "peacekeepers" to keep it in power.

That doesn't mean it is what he actually intends to do. Like his US protege Trumputin, Putin loves lying, and the more brash and absurd, the better.
