You don't think that China, Saudi Arabia, Africa or S. America are part of the world? Lots of countries understand that Russia IS REACTING to US/NATO aggression - and Eastward Expansion, right up to their Borders ... Are you aware that the US orchestrated a NAZI Coup in Ukraine in 2014, after a CIA Color Revolution in 2004 got reversed, in a Democratic election?
There's been a horrific war going on in Eastern Ukraine, since 2014. At least 14,000 people killed, and 50,000 wounded - mostly ethnically Russian civilians, who had VOTED to leave Ukraine, and form autonomous Republics, where language that they speak isn't OUTLAWED. Where they won't be ruled over, by LITERAL NAZIS - who want them dead, and ethnically cleansed from the land where they were born, and where there ancestors fought against the Third Reich.
Go look up Stepan Bandera and Roman Shukhevych. Since the 2014 Coup - those two murderous NAZI Psychopaths, have been officially rehabilitated, and cast as National Heroes of Ukraine (a trend which began after the 2004 Color Revolution, as the Nazis were fostered and assisted by the CIA, and internal rightwing forces).
There is clearly more to this story, than you're aware of. TheGrayzone.com, Mintpressnews.com (Dan Cohen and Alan Macleod) are good places to start learning what this conflict is really about. GlobalResearch.ca has also got solid coverage, that avoids the propaganda onslaught in the US and Western legacy (aka OPERATION MOCKINGBIRD) media. At least the first two of those have youtube channels, still.

(That this article has recently been censored by The Nation Magazine - shows you that the propaganda push is in full swing. The Nation's publisher, is the widow of the esteemed author, who wrote it.)
