From Ukraine last year, to Nagorno-Karabakh last month and now Israel, it really does feel like there's a trend of people becoming more comfortable with using large-scale unilateral violence to solve problems. That trend itself greatly worries me; each instance normalizes and legitimizes the next.

Maybe it's a strategy to destabilize every country involved with "the west", especially USA, to overwhelm. NATO and its allies can't help everywhere all at once.. 
This is all very worrying.. If this is a trend how much different is it from being WW3?
