These countries were under the thumb of Soviet Russia not all that long ago. It's pretty common to find people that are still a bit bitter about Russians. They usually like the Germans much more than Russians. One of my Czech friends put it like this, if someone came up to them in the street and asked them for directions in Russian they'd talk to them in English instead.
The biggest issue is even if you had footage showing Russia firing an shell and it landing across the border it doesn't matter. Putin clearly doesn't care. NATO states aren't going to risk blood and treasure on Ukraine. They need Russian energy for the Winter. The French are still going to complete the sale of some Warships to Russia.
Meanwhile, back in America we've launched a bunch of sanctions. What Russian imports will disappear off the shelves? Guns and Vodka. I think they'll survive.
