Why has the world been so changed since last year?

I am pretty worrying about all these awful happenings in the middle easters area and that seems truly pathetic and heart-touching if civilians were being brutally and vulnerably murdered.. I missed the last year which one the real peace had dominated the world.. I haven't been feeling myself so well as the same as in the past especially like even last year.. Does anyone agree with me?
