From time to time over the years, the eminent historian Daniel Pipes has lamented that treason, not just as a crime but as a concept, appears defunct in the West. The question of bringing treason charges against jihadists has been raised from time to time. Often its very asking proves Dr. Pipes’s point: Most radical Islamic terrorists are not American...

In the United States of America, rioting to stop free speech is unlawful and reprehensible. Period. Full stop. It’s not “understandable.” It’s not excusable. There should be no tolerance and no sympathy for people who pepper-spray young women, beat bystanders senseless, and tear up property because they’re mad that another human being is speaking. Last night’s spectacle in Berkeley, Calif.,...

The signs of popular dissent from President Trump’s opening volley of actions have been plain to see on the nation’s streets, at airports in the aftermath of his refu­gee and visa ban, and in the blizzard of outrage on social media. But there’s another level of resistance to the new president that is less visible and potentially more troublesome to...

Tuesday night, President Donald Trump announced his nomination for the Supreme Court vacancy left by the unexpected death of Justice Antonin Scalia last February. Trump nominated Judge Neil M. Gorsuch of the U.S. Court of Appeals for the 10th Circuit. With this nomination, Trump held to the promise he made on the campaign trail to select a nominee from a list of...

One of the sharpest criticisms that comes against Bible-quoting, conservative Christians is that we are hypocrites, failing to live by the very book that we so zealously quote. Sadly, that criticism is often true. To give just one example (and as I’ve said countless times), no-fault, heterosexual divorce in the evangelical church has done more to undermine marriage than all...

This week, the Trump administration botched the rollout of a relatively moderate immigration and refugee executive order that would have paused immigration from seven Muslim-majority countries for a set period of time and ended Syrian-refugee immigration indefinitely. Instead of vetting the executive order or coordinating with the relevant agencies, the Trump team simply unleashed it, leading to widespread chaos at...

WASHINGTON — For the White House, President Trump’s first nomination to the Supreme Court is partly about getting the chance to make a second. In tapping Judge Neil M. Gorsuch for an open seat, Mr. Trump chose a candidate with the potential to reassure Justice Anthony M. Kennedy, the swing vote who holds the balance of power on the court,...

Donald Trump should push the nuclear button. No, not the one that launches actual nuclear weapons. I mean the one that blows up Democratic obstruction to his Supreme Court nominee and puts a reliable conservative on the court to replace justice Antonin Scalia. There is no reason for Trump and Senate Republicans not to go nuclear. Senate Democrats have already...

As British Prime Minister Theresa May becomes the first foreign leader to visit President Trump, it is a good time to consider that Margaret Thatcher, much more than Ronald Reagan, is the real model for the Trump presidency. Trump’s inaugural address last Friday had the directness and confrontational tone of a Thatcher speech. The president was clear that he stood...

President Trump’s temporary ban on entry into the U.S. by various categories of aliens has caused a firestorm. That owes in part to the rash implementation of perfectly legal restrictions, but the hysteria is out of proportion to the minimal harm actually done. One of the most dismaying parts of the debate has been the banter over whether Trump has...
