Might vs. Right

We often quote the phrase "Might is right". Towards understanding of the term "right" I came across an article of Max Stirner. He believes:

Right can be bestowed only by a spirit, be it the spirit of nature or that of the species, of mankind, the Spirit of God or that of His Holiness or His Highness, etc."
I do not demand any right, therefore I need not recognize any either. What I can get by force I get by force, and what I do not get by force I have no right to, nor do I give myself airs, or consolation, with my imprescriptible right. With absolute right, right itself passes away; the dominion of the "concept of right" is cancelled at the same time. For it is not to be forgotten that hitherto concepts, ideas, or principles ruled us, and that among these rulers the concept of right, or of justice, played one of the most important parts.

Entitled or unentitled -- that does not concern me, if I am only powerful, I am of myself empowered, and need no other empowering or entitling. Right -- is a wheel in the head, put there by a spook; power -- that am I myself, I am the powerful one and owner of power. Right is above me, is absolute, and exists in one higher, as whose grace it flows to me: right is a gift of grace from the judge; power and might exist only in me the powerful and mighty.

That gives one more reason to believe in the phrase "Might is right". And don't the world super powers think in this way?
