MILWAUKEE, July 19 — Donald Trump’s speech accepting the Republican presidential nomination lasted one hour and 32 minutes, the longest in modern United States history. Here are five key moments and themes punctuating the often rambling delivery.

Fight, fight!

Trump’s speech had been billed by aides as set to herald a new, softer tone in the wake of surviving his assassination attempt last Saturday.

But the vibe was often harsh — and literally pugilistic.

"Fight, fight!” was the chant led by Trump’s son Eric before the big speech, in homage to his father’s words on the rally stage last weekend, as he got up from being injured in the shooting.

The man introducing Trump to the podium was none other than his friend Dana White, chief executive of the wildly popular and bloody UFC martial arts network.

Before White, the crowd got to hear from colourful 1980s pro-wrestler Hulk Hogan.

Kiss, kiss

There were kisses too. One was blown by Trump to Hulk Hogan in appreciation.

Trump also paid homage by kissing the helmet of firefighter Corey Comperatore, who was killed during the shooting at last weekend’s rally. Trump asked the crowd to observe a moment of silence for the victim, whose firefighter’s uniform was displayed on the stage.

At the end of the speech, Trump was joined by his wife Melania, who has been notably absent during his campaign for a return to the White House in November. He took her hand and pecked her on the cheek.

God

Trump has never been much of a churchgoer in public, even as president, but he attributed his survival of the shooting to God.

"I stand before you in this arena only by the grace of Almighty God,” he said.

"There was blood pouring everywhere and yet in a certain way I felt very safe because I had God on my side.”

His narrow escape has been heralded by many supporters as a sign that Trump has even been chosen by God. One of the warm-up speakers was evangelist preacher Franklin Graham — whose father was spiritual adviser to multiple US presidents.
