Perhaps because the Ukraine is a sovereign country?
Because it would garner the ire of other nations.
What happened to the good old days when the “aid” to the rebels was actually hidden not shown on CNN?
As I look at russia and their assistance and such to reclaim people and lands that are “Russian”, I am reminded of the sudatenland and czechoslovakia in the early days of WWII. This is more than a little similar to the Nazi invasions of those countries.
And Russia isn’t exactly innocent here, they have tried similar things in the past, Finland for example, pretty much the entire slavic world at one point in the last century.
Gent I know, Russian in Denver, has nothing good to say about Putin or the situation in the Ukraine and russian involvement. But then he’s not in russia and can speak freely without being jailed or executed.
