Just six weeks apart in the spring of 1981, Pope John Paul II and President ­Ronald Reagan took bullets from would-be assassins.

Few realized at the time how close both men came to dying.

Surviving these near-death experiences created a singular bond between the pope and the president that ­historians have failed to appreciate.

When John Paul II and Reagan met only a year later, they confided to each other a shared conviction: that God had spared their lives for a ­reason. That reason? To defeat Communism. In private, Reagan had a name for this: “The DP” - the Divine Plan.

It has become fashionable to see the collapse of the Soviet empire as inevitable. Hardly.

In this riveting book, bestselling author Paul Kengor and writer-­director Robert Orlando show what it took to end the Cold War: leaders who refused to accept that hundreds of ­millions must suffer under totalitarian ­Communism.

And no leaders proved more important than the pope and the president.

Two men who seemed to have little in common developed an extraordinary bond - including a spiritual bond between the Catholic pope and Protestant president. And their shared core convictions drove them to confront Communism.

To tell the full story of the dramatic closing act of the Cold War, Kengor and Orlando draw on their exhaustive research and exclusive interviews with more than a dozen experts, including well-known historians Douglas Brinkley; H. W. Brands; Anne Applebaum; Stephen Kotkin; John O’Sullivan; Craig Shirley, the leading biographer of John Paul II; George Weigel; close Reagan advisers Richard V. Allen and James Rosebush; and Cardinal Timothy Dolan and Bishop Robert Barron.

You can’t understand Pope John Paul II and President Ronald Reagan - or how the Cold War came to such a swift and peaceful end - without understanding how much faith they put in the Divine Plan.
