Both sides are indicating an escalation, though who escalated is in dispute. (Though the motive for Ukraine to escalate when Russia has massed troops on their border and on the same day that Russia recognizes the breakaway republics is somewhat obscure, while the motive for Russia-backed separatists to do so is blindingly obvious.)
So there's a situation where Ukraine isn't a well defined entity anymore. This is, of course, absolutely great for Russia, but it's very concerning.
The invasion in 2014 which is still ongoing were Russian soldiers dressed as separatists and rebels so I suspect we will never see Russia proper.
It was all over US media yesterday.
It's Ukraine and Russian backed Ukraine separatist regions (who are currently evacuating civilians to Russia in expectation of more conflict).
I do not believe we will ever see Russia Proper. The ongoing invasion from 2014 had/has soldiers dressed as separatists.
