Just hours after his domestic policy megabill squeaked through Congress on Thursday, President Trump stood before a crowd of supporters and marveled at how well it all seemed to be going for him lately.

“We had a good two weeks, right?” Mr. Trump said at the Iowa State Fairgrounds, where he was taking a quick victory lap. “This has to be the best two weeks — has anybody ever had a better two weeks than this?”

Yes, in the history of Washington there has probably been a better two weeks than this. But there is no doubt that, at least on his terms, Mr. Trump can claim accomplishments one after another.

His order to bomb Iran set back that nation’s nuclear program without triggering a broader conflict. He flew to Europe and got NATO members to pony up more money for their own defense. The Supreme Court continued a pattern of backing his assertions of executive power. The economy showed resilience in the face of predictions that his tariffs would send it spiraling, and the stock market hit record highs.

Illegal border crossings plummeted last month to the lowest numbers seen in decades. The parent company of CBS agreed to pay $16 million to settle his complaint that “60 Minutes” had favored his opponent in last year’s election. And passage of his signature legislation by the House and the Senate demonstrated once more his dominance of the Republican Party and set fiscal and social policy for years or decades to come.

The mood at the White House at the moment might be described as aggressively chipper. Presidential aides are practically whistling while they walk the halls of the West Wing. And nobody seems happier than the boss.
