It's pretty mainstream news if you are in Europe.
But in all fairness, the Ukraine borders the EU and there are political ties or ambitions there concerning the EU. No, I don't know all the details and I wont pretend to, but ultimately, it affects the EU. The US, on the other hand, is a world away and frankly what goes on in the Ukraine is not exactly a big deal to the US or its people. Yes, on a being informed of big events in the world level, it should be reported in the US, but I can understand the US not being that interested. Im sure there are levels of concern for the US, but its a much bigger deal to us in Europe.
