Let's start our look around the world with Thursday's emotional ceremony in Normandy, France, to mark the 75th anniversary of the D-Day landings.
D-Day was the invasion by American and British troops into Nazi-occupied northern France that turned the tide of the Second World War, but it came at the cost of so many young men's lives.
The leaders of several countries were at the ceremony, including the leaders of the U.S., France, the UK and Canada.
For more on this and other news around the world, let's turn to our Hong Yoo.
So Yoo, European leaders highlighted the importance of alliance during their speeches. Was President Trump's speech along the same track?
Like you said Mark, European leaders tried to emphasize importance of alliances to President Trump, saying it was alliance between western countries that have kept the continent at peace for years.
French President Emmanuel Macron praised the ambition and bravery of the U.S. when they had fought for universal values and then he addressed Trump saying that, by staying united, they can overcome any challenges ahead.
"We want to show ourselves to be worthy of the heritage of peace that we have received from you, our debt, worthy of the promise of Normandy. And being worthy of the promise of Normandy is to never forget that when free people unite they can conquer any challenge."
Queen Elizabeth II stressed the need to maintain "close and long-standing friendship" as they were facing new challenges in the 21st century during her state banquet with Trump earlier in the week.
Take a look.
"After the shared sacrifices of the Second World War, Britain and the United States worked with other allies to build an assembly of international institutions, to ensure that the horrors of conflict would never be repeated. While the world has changed, we are forever mindful of the original purpose of these structures: nations working together to safeguard a hard-won peace."
Despite their efforts, President Trump at the ceremony in Normandy on Thursday offered little embrace to the transatlantic alliance.
Instead, he chose to mostly share the heroic stories of U.S. veterans who put their lives on the line during D-Day.
European leaders had hoped Trump visit to Normandy to have worked as a reminder of the value of their transatlantic alliance.
But with the race for the second term of presidency to begin soon, President Trump will likely continue his America First policies to keep his base fired up.
