I do have the advantage over you of living in a community with a large amount of both Russians and Ukrainians and knowing some for many years. They are almost indistinguishable from one another to people who are not familiar with them.==
Because we are mixed together for centuries. I’m myself partially Russian and Ukrainian too. There is a third part called Byelorussians. We all 3 came from one source: middle-age Rus.
The difference is very subtle. Actually it more like between Yankees and Southerners. Russians are like Yankees.
Ukrainians and Belorussians are more pro-westerns but Russians are pro-independent from West.
Also Russia has now about 30,000 ukie POWs. But Ukraine has only 1,000. SO you may understand WHO really kills unarmed.
