“The Holocaust was about the Jews,” former Reagan speechwriter John Podhoretz wrote in Commentary this weekend, “There is no ‘proud’ way to offer a remembrance of the Holocaust that does not reflect that simple, awful, world-historical fact.”

On Friday afternoon, of course, Trump signed an executive order barring refugees and citizens of seven majority Muslim countries from entering the United States. It was his way of making good on a campaign promise to ban Muslims from the country.

The order also said it would eventually give priority to religious minorities from these countries. And if anyone doubted who that meant, Trump gave an interview Friday to the Christian Broadcasting Network, explaining that its goal was indeed to help Christians. Fortunately, many Christian leaders are opposing the policy.

I expect that Trump’s attempts to undermine the First Amendment will ultimately fail. But they’re not guaranteed to fail. He is the president, and he has tremendous power.

The attempts will fail only if Americans work to defeat the White House’s flirtations with theocracy — as so many people began to do this weekend. This passionate, creative opposition may help explain Trump’s weakening of the ban on Sunday. Yet the struggle to defend American values is clearly going to be a long and difficult one.
