I'm not sure that it is really similar. I would translate "Wer macht hat recht" to something more like "the creator knows best" or "the creator gets to choose". "History is written by the winners." has, I think a less creative context. Perhaps because history is what is written after wars, conquests and other applications of violence. The word "winners" requires and implies losers. Creation requires neither.
Not similar at all, and an absurd comparison. The former is a value/moral judgement while the latter is an empirical observation about how history is written, and not at all an embrace of such a supposed fact (which would effectively translate to “might makes right”).
> It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows the great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.
Closest thing in English that I could think of: history is written by the winners. Similar concept.
