President Donald Trump mourned the loss of America’s military service members who have lost their lives defending this country during his Memorial Day address at Arlington National Cemetery Monday. 

Prior to his comments, he placed a wreath at the Tomb of the Unknown Soldier, which contains the remains of unidentified war dead from World War I, World War II and the Korean War.

During his address, he mourned the deaths of the 13 service members who died during the current war with Iran. The family of at least one of those service members was in attendance. 

"These incredible men and women gave their lives to ensure that the world's number one state sponsor of terror will never have a nuclear weapon. Oh, and they won't. They will never have a nuclear weapon. I'm sure you know that one," Trump said.

President Trump also cited a 97-year-old veteran of the Battle of the Bulge who attended the Memorial Day ceremony. 

"At 15, Harry Miller lied about his age to enlist and was soon fighting to stop the SS Panzer divisions, as part of the famed 740th Tank Battalion — the Daredevils, they were called — of which he is among the last surviving members at 97 years old," Trump said.

"Within six months after the battle, Harry's unit lost 42 comrades. He's remembering them today.

"Sgt. Miller, it is a true honor to have you with us."

"In two wars recently, we've lost a total of 13 service members. In Venezuela, which was a complete and total victory ... we took that over in one day, lost no one. In Operation Epic Fury, we lost 13 wonderful souls, wonderful special people."

Trump said this was the fifth time he has attended this event as president.
