President Joe Biden on Thursday used the 80th anniversary of D-Day to warn against the spread of isolationism and to promise that the U.S. would “not walk away” from Ukraine.

Speaking before a crowd of aging WWII veterans, many over 100 years old and wheelchair bound, Biden pointed to the beaches of Normandy, where he spoke, as “a powerful illustration of how alliances make us stronger. It was, he remarked, “a lesson that I pray Americans never forget.”

President Biden used D-Day commemorations along the windswept beaches of Normandy to warn against the spread of isolationism in the U.S. and to defend decades of trans-Atlantic security ties that are facing fresh conflicts and rising authoritarianism.

Biden delivered the remarks before French President Emmanuel Macron and a crowd of dignitaries and aging veterans who had gathered at the Normandy American Cemetery in France on Thursday to mark the 80th anniversary of Operation Overlord, the largest amphibious invasion in history.

President Donald Trump delivered sobering remarks in Normandy, France, Thursday to mark the 75th anniversary of the D-Day landings there that set into motion the final phase of World War II.

At the Normandy American Cemetery and Memorial, Trump told the stories of American soldiers and other key figures who helped make the invasion a success on June 6, 1944.

Here are some of the key moments from Trump's speech:

'You are among the very greatest Americans who will ever live'

President Trump marked the 75th anniversary of the D-Day invasion in Normandy at a ceremony at the grave site of more than 9,380 American service members who were killed in the World War II landings and the operations that followed.

“To the men that sit behind me and to the boys that rest in the field before me, your example will never grow old,” Mr. Trump said, with an audience of veterans behind him. “Your legend will never die.”

Members of the liberal media had high praises for President Donald Trump's words at the 75th commemoration of D-Day celebration in Normandy, including MSNBC's "Morning Joe" host Joe Scarborough calling it the "strongest speech of his presidency" and CNN's Jim Acosta lauding it as his most "on-message moment."

On this day, June 6, 75 years ago, my dad was awakened early — or, more accurately, late.

Just about midnight, he and his crewmates were stirred roughly from a much too short sleep and told to get ready for what would be Mission #10 of the 25 expected for their B-17 bomber.

President Trump’s speech on Thursday honoring the brave Allied fighters who "stood in the fires of hell" on the 75th anniversary of D-Day drew unexpected acclaim from two of his biggest mainstream media critics: CNN’s Jim Acosta and MSNBC’s Joe Scarborough.

“This is perhaps the most on-message moment of Donald Trump’s presidency today. We were all wondering if he would veer from his remarks, go off of his script but he stayed on script, stayed on message and, I think, rose to the moment,” Acosta said on CNN immediately following the speech.

French president praises multilateralism of Nato and EU while offering gratitude to US

France’s president, Emmanuel Macron, has appealed directly to Donald Trump to fulfil the “promise of Normandy” by embracing pillars of the postwar peace such as the European Union and Nato as the two leaders marked the D-day landings 75 years ago.

In a speech that trod a fine diplomatic line, Macron offered both sincere expressions of gratitude for the valour of US troops in the second world war and vehement calls for the White House to re-engage with the principles of multilateralism.
