The comments come just days after Mr Trump visited Mr Macron at the Élysée Palace in Paris on the occasion of the First World War Armistice 100 year commemorations, and called the French leader "a good friend", with whom he shares "similar views".
In a flurry of early morning tweets on Tuesday, Mr Trump said the USA saved Parisians from "learning German" during the Second World War, blasted "not fair" French tariffs on American wines, and goaded Mr Macron over his "very low" approval ratings.
Trump's previously friendly relationship with Macron appears to be deteriorating, however, as the French leader decries the rise of nationalism the US president has embraced.
Trump has declared himself a "nationalist", with an America First outlook on global relations.

US President Donald Trump has unleashed an extraordinary attack on Mr Emmanuel Macron, mocking the French President's approval rating and lashing him over European defence proposals which enjoyed a crucial new boost from Germany.
During his visit, the USA president was widely criticised for failing to visit the Aisne-Marne American cemetery, which the White House later said was down to visibility being too poor for his helicopter and Mr Trump not wanting to disrupt the Paris traffic with his motorcade. "Pay for North Atlantic Treaty Organisation or not!" he added.
Almost all United States wine exports to major markets, including the European Union - of which France is a part - face tariffs, according to the Wine Institute, which represents California winemakers in Washington on matters of tax, trade and regulatory issues.
He defended his much-criticised absence from a commemoration event on Saturday, saying the US Secret Service had vetoed driving to the venue because of logistics.
White House Director of Strategic Communications Mercedes Schlapp, meanwhile, cast Trump's Paris trip in a positive light. Macron has anti-nationalist allies in several progressive Western European nations.
The dispute among friends boiled over into a full-blown diplomatic conflict, with Trump venting about the tax treatment of American-made versus French wine and complaining about the the existing North Atlantic Treaty Organisation alliance. France played an important role in the US War of Independence and the US supported France during two world wars. "For the sake of truth, Pres.@EmmanuelMacron didn't say that European Union needed an army "against the US".
President Donald Trump struck a serious blow in his war of words with French President Emmanuel Macron Tuesday, firing back at the French leader for comments he made defending his country's meager contributions to NATO's defense budget by reminding Macron about France's illustrious military history. Many others posted photos and reference to the soccer victory.
"The United States are our historic ally and will continue to be".
The weekend started uncomfortably.
Early Tuesday morning, Trump tweeted, "Emmanuel Macron suggests building its own army to protect Europe against the U.S., China and Russian Federation".
He went on the interview to talk about the need for a European army, citing the threat from Russian Federation and saying that Europe needed to "better defend itself by itself, without depending exclusively on the United States".
French officials said the row was based on a misunderstanding and that Macron was simply making a case for reducing Europe´s military dependence on the United States.
