It doesn't actually solve anything, rather it makes the baseline lower by hurting everyone. I.e., it's an anti-solution - something that actively makes things worse, and can only make things worse, but masquerades as a solution.

An example of an anti-solution is lowering crime by making something that was illegal no longer illegal (see: public transit vs automobiles). Or, reducing the incidence of something by making it illegal while simultaneously increasing it's necessity (see: abortion). Or, solving wage inequality by protesting minimum wage increases.

It makes the whole world blind

agreeing with the point the question makes here; the game theory of global politics does not work with the same morals that we prescribe individual people
