President Donald J. Trump reminded Kansas on Monday night what American strength looks like. “All of us here tonight represent the greatest nation in the world,” he told the crowd in Park City.

It was not that way two years ago, the President said. “Frankly, our nation was not so great two years ago. It was an embarrassment. We had a president that couldn’t find his way off a stage,” Trump said of Joe Biden. “Couldn’t walk up the stairs. Couldn’t walk down the stairs.”

Now, he said, America is back on top. “We’re a country with the most extraordinary people, the most incredible art, the most advanced technology, the most exceptional culture ever to exist,” Trump said. “And perhaps most importantly, the greatest, we have the greatest military.” The crowd broke in: “Thank you, President Trump.”

Trump said he rebuilt the armed forces in his first term, and the world has seen the results. “And if you have any questions about that, just ask Venezuela or ask Iran,” he said. “They’ll tell you about it.”

That is peace through strength. The President rebuilt the military, America’s enemies have learned what it can do, and the greatest nation in the world is leading again.
