The White House announced on Thursday that next year’s Group of 7 summit meeting will be held at the Trump Doral, the golf resort the president owns in Miami. This editorial was originally published on Aug. 26 when Mr. Trump first proposed the idea.

The Doral golf resort near Miami has been struggling ever since its owner, Donald Trump, kicke d off his bid for the presidency. In the span of two years , its net operating income fell by almost 70 percent. Maybe that’s why what passes for presidential diplomacy these days includes this pitch, made by Mr. Trump just after the Group of 7 summit in Biarritz, France, on Monday:

“With Doral, we have a series of magnificent buildings, we call them bungalows, they each hold from 50 to 70 — very luxurious rooms with magnificent views. We have incredible conference rooms, incredible restaurants,” Mr. Trump boasted at a news conference, explaining why Doral should host the next Group of 7 meeting. “And what we have also is Miami and we have many hundreds of acres so that in terms of parking, in terms of all of the things that you need, the ballrooms are among the biggest in Florida and the best.”

A follow-up tweet by the official White House account seemed to present the site selection as a done deal.

Few people would doubt that a Trump resort had adequate space — and parking — to accommodate such a gathering. Mr. Trump has built his brand on the core principle that bigger is better.
