Boomarang, what goes around might come around

1st of all, apologize for the ugly sketch of boomerang :-)
My history is no good either but i know this traditional wooden stick is used by Australia aborigines for hunting, after the launch this stick will hit the prey and then come back to the hand of thrower

I hope this analogy is simple and yet easy to follow.
I do not know who launch this falling boomerang first to cut almost all the oil producing countries on its way to maximum distance, but ultimately this boomerang knife will come back faster to hurt the launcher right?

Quess which country i purposely left out to be the last one get hurt??

P.S. Three months ago, i didn't really know my first analysis of the crude oil chart "Consolidation about to End" could be that deadly!
