Not all similar positions are wins. In this position, Black draws because he can safely check from the side. For this defense to work, there must be at least three files between the defending rook and the attacking king, and the defending king must be positioned such that it doesn't block the checks; that is, the defending king is on the "short side" of the pawn (the one with fewer files between the pawn and the edge of the board) (de la Villa 2008:127–28). (See the "short side defense" at rook and pawn versus rook endgame for more details.)

“What arouses the indignation of the honest satirist is not, unless the man is a prig, the fact that people in positions of power or influence behave idiotically, or even that they behave wickedly. It is that they conspire successfully to impose upon the public a picture of themselves as so very sagacious, honest and well-intentioned.”
—Claud Cockburn (1904–1981)
“I am not willing to be drawn further into the toils. I cannot accede to the acceptance of gifts upon terms which take the educational policy of the university out of the hands of the Trustees and Faculty and permit it to be determined by those who give money.”
—Woodrow Wilson (1856–1924)
