MICHAEL BARONE: Trump’s State of the Union was surprisingly reflective and disciplined.

“ This year,” President Trump stated in the seventh paragraph of his widely viewed and positively rated State of the Union address, “America will recognize two important anniversaries that show us the majesty of America’s mission and the power of American pride.”

“On D-Day, June 6, 1944, 15,000 young American men jumped from the sky and 60,000 more stormed in from the sea,” he said. And then in July 1969, “brave young pilots flew a quarter of a million miles through space to plant the American flag on the face of the moon.”

None of the commentators I’ve seen have questioned why Trump chose to spotlight these events. He is not usually given to historical references; even his trademark slogan is vague about just when American was great. Celebrating others’ past achievements has not been his thing. But beginning the speech by celebrating these two American triumphs provided a shrewd framing with the potential to elevate his image. . . .

The larger point made at the beginning, underlined by the appearance of three D-Day veterans and astronaut Buzz Aldrin, is a refutation, without specific mention, of an argument that underlies so much of the upscale loathing of Trump and his politics.

That is the idea—call it the cosmopolitan argument—that nationalism is always bad, a primitive and unsophisticated bias in favor of the home team, a short step (if that) from Nazism. The argument is attractive to many because it makes them feel more sophisticated than the rubes who always praise America.

But the argument is weak if you know more history. “I ask you to join with me in prayer,” Franklin Roosevelt said in his radio fireside chat on the evening of D-Day, “Almighty God: Our sons, pride of our Nation, this day have set upon a mighty endeavor, a struggle to preserve our Republic, our religion and our civilization, and to set free a suffering humanity.”

Yes, it’s nationalism, and it’s a prayer. Roosevelt mentioned allies only at the end and in passing. Trump underscored Roosevelt’s assertion that American nationalism is for the good by introducing (and leading the singing of Happy Birthday) for 81-year-old Holocaust survivor Judah Samet, recalling how, when their train “suddenly screeched to a halt, a soldier appeared. Judah’s family braced for the worst. Then his father cried out with joy, ‘It’s the Americans!”

Today, Trump argued, American nationalism continues to be benign, whether it’s trying to stop Iran’s genocidal nuclear ambitions by withdrawing from the Obama nuclear deal or it’s seeking to oust the disastrous Nicolas Maduro dictatorship in Venezuela.

This State of the Union can also be seen as a refutation of the identity politics conceit that white cisgendered males are inevitably the villains of history, ever-ready to oppress women and people of color, and that virtue inheres only in their intended victims.

That just doesn’t compute when you watch Trump’s salute of SWAT officer Timothy Matson, who “raced into gunfire and was shot seven times” and brought down the hateful murderer at the Tree of Life Synagogue in Pittsburgh.

There was less emphasis than many predicted on divisive issues — the border “barrier,” as Trump has taken to calling it, and abortion. On these, Democrats are at risk of getting out on flimsy limbs.

The reflection and discipline are less surprising if you’ve been paying close attention.
