Ukraine is an excellent example. Look at all of the ways they're attacking Russia internationally, even using "terroristic" tactics. It's justified because they're fighting for their survival.
The West has been bent on Russia's destruction since the cold war, and it didn't end with the fall of the USSR.
I won't bother with a point by point, but take the death toll of MH17. The US has probably killed 10x that amount of innocent people as collateral damage while striking weddings and religious services. And yet it's not brought up in lists about how dangerous we are.
As for whether Russia has anything to fear from the west, well, just look at Venezuela and Iran. It's a good indication of what we'd like to do to them.
