"Reagan’s success owed less to luck as such than to recognizing and using luck. He inherited a defense buildup started under his predecessor Jimmy Carter as well as a burst of high-tech creativity which that buildup nourished. In Paul Volcker he inherited a head of the Federal Reserve who had pushed interest rates to double digits a year before Reagan took office, a brutal recession-causing step that by early in the new presidency had cut inflation to 3.5 percent, so clearing a path to the long economic boom that lasted into the new century. Reagan inherited a superpower rivalry that the United States was on course to win as its Soviet adversary, mired in its own failures and shadowed by a rising China, began to implode. With practiced grace and skill, Reagan made the most of those opportunities. He knew when to push at an open door, calling out dramatically in Berlin in June 1987, “Mr. Gorbachev, tear down this wall.” Reagan left office (January 1989) at a moment of American contentment and strategic success that would have shone credit on a lesser politician. As it was, skill, luck, and timing confirmed him among contemporaries as a historic figure. On the American right, all factions could claim Reagan for their own. By contrast, Republicans who later followed him in the White House, George W. Bush (2001–9) and Donald Trump (elected 2016) divided their own party as successfully as they held off the Democrats."
