The article is from Radio Free Europe, for Gosh's sake! Are you serious?!
Just what the Ukrainians need, huh? Americans telling them what to do. Because it always ends up so well when the USA interferes on other continents.

It wants Ukraine to lick the US butt, while being a super-cheap outsourcing country, in debt to US banks and hosting a few US military bases on the border to Russia.
