The power of the American presidency is like none other on earth. It is a certainty that Trump’s worst vices—his crudeness, his infantile attacks on critics, personal grudges, unchecked egotism—would be magnified the day he took office. Yes, try to imagine Trump with his finger on the nuclear button without trembling.

The rueful lessons of the Vietnam War, especially their roots in the hubris of modern liberalism, remain largely forgotten.

Last week’s startling confession by White House operative Ben Rhodes—that the Obama administration lied to the American people about its dealings with Iran to secure a nuclear agreement—not only confirms the perception of a mendacious and arrogant presidency. It exposes a feverish and even delusional frame of mind: an uncompromising revulsion for war that has undermined American security and invited a cascade of extremism, violence, and human suffering.

Throughout his presidency, Obama has appeared profoundly uncomfortable with the qualities most often associated with Churchill: martial resolve, moral clarity, and supreme confidence in the transcendent ideals of Western Civilization.

As the Obama White House sees it, much of the D.C. foreign policy “establishment” is “doing the bidding of their Arab and pro-Israel funders.” Translation: foreign policy experts who disagree with the president do not have the best interests of the United States in mind. This week some members of the so-called foreign policy establishment fired back.

Why do the Taliban believe they can impose their radical, Islamic ideology upon a nation of 182 million people? Because Pakistan, like other Muslim-majority states, enforces a legal regime that criminalizes apostasy.

Despite a posture of inquiry, Jeffrey Goldberg’s journalistic empathy dissolves into rank advocacy: journalism as echo chamber. Here is what access to ultimate political power can breed: something that rings false from beginning to end, something much closer to propaganda than truth-seeking.

Exactly when has the determination to “exhaust” all the alternatives to military force ever brought a genocidal regime to its knees? Never.

In every year of Mr. Obama’s presidency, without exception, the cause of freedom has been in retreat around the world.

Last month about 300 muftis, theologians, and scholars held a conference in Marrakesh, Morocco to address the problem of violence in Islamic states. The result is the Marrakesh Declaration, a 750-word document calling on Muslim countries to guarantee “full protection for the rights and liberties to all religious groups” and “confront all forms of religious bigotry.” Yet the crisis in modern Islam is that its leaders still steadfastly refuse to confront their violent past.
