Make Denmark angry. Make Norway angry. Make NATO’s leaders angry.
President Donald Trump’s relentless and escalating drive to acquire Greenland from Denmark, whose authorities – along with that of Greenland – emphatically rejects the thought, has unnerved, offended and outraged leaders of nations thought-about allies for many years.
It’s the newest, and maybe most vital, eruption of an attitude of disdain towards allies that has grow to be a hallmark of the second Trump administration, which has espoused an America First approach to the world.
Trump, Vice President JD Vance and Defense Secretary Pete Hegseth have all mentioned a variety of issues about longtime allies which have caused frustration and outright friction among the many leaders of these international locations. The newest discord over Greenland might have an effect on the functioning and even existence of NATO, the post-World Battle II alliance of Western nations that “gained the Chilly Battle and led the globe,” as a latest Wall Avenue Journal story put it.
As a former diplomat, I’m conscious that how the U.S. treats its allies has been an important query in each presidency, since George Washington turned the nation’s first chief govt. On his manner out of that job, Washington mentioned one thing that Trump, Vance and their fellow America First advocates would in all probability embrace.
In what’s generally known as his “Farewell Tackle,” Washington warned Americans against “entangling alliances.” Washington wished America to deal with all nations pretty, and warned towards each everlasting friendships and everlasting enemies.
The irony is that Washington would by no means have grow to be president with out the help of the not-yet-United-States’ first ally, France.
In 1778, after two years of brilliant diplomacy by Benjamin Franklin, the not-yet-United States and the Kingdom of France signed a treaty of alliance because the American Colonies struggled to win their war for independence from Britain.
France despatched soldiers, money and ships to the American revolutionaries. Inside three years, after a significant intervention by the French fleet, the battle of Yorktown in 1781 effectively ended the war and America was impartial.
Isolationism, then battle
American political leaders largely heeded Washington’s warning towards alliances all through the 1800s. The Atlantic Ocean shielded the younger nation from Europe’s issues and plenty of conflicts; America’s closest neighbors had smaller populations and fewer navy may.
Except for the War of 1812, in which the U.S. fought the British, America largely discovered itself shielded from the skin world’s issues.
That started to vary when Europe descended into the brutality of World Battle I.
Initially, American politicians averted involvement. What would at the moment be referred to as an isolationist motion was robust; its supporters felt that the European battle was being waged for the advantage of big business.
Nevertheless it was laborious for the united statesto keep neutrality. German submarines sank ships crossing the Atlantic carrying American passengers. The economies of a few of America’s largest buying and selling companions had been in shreds; the democracies of Britain, France and different European international locations had been in danger.

President Woodrow Wilson led the U.S. into the war in 1917 as an ally of the Western European nations. When he requested Congress for a declaration of battle, Wilson asserted the worth of like-minded allies: “A steadfast live performance for peace can by no means be maintained besides by a partnership of democratic nations.”
Instantly after the battle, the Allies – led by the U.S., France and Britain – stayed collectively to craft the peace agreements, feed the war-ravaged parts of Europe and intervene in Russia after the Communist Revolution there.
Prosperity got here together with the peace, serving to the U.S. shortly grow to be a worldwide financial energy.
Nonetheless, inside a couple of years, American politicians returned to traditional isolationism in political and military matters and continued this perspective nicely into the Thirties. The worldwide Nice Despair that started in 1929 was blamed on vulnerabilities within the international financial system, and there was a strong sentiment amongst People that the U.S. ought to repair its inside issues reasonably than help Europe with its issues.
Alliance counters fascism
As both Hitler and Japan started to assault their neighbors within the late Thirties, it turned clear to President Franklin Roosevelt and different American navy and political leaders that the U.S. would get caught up in World Battle II. If nothing else, airplanes had erased America’s capacity to cover behind the Atlantic Ocean.
Although public opinion was divided, the U.S. started sending arms and other assistance to Britain and quietly started navy planning with London. This was although the U.S. was formally neutral, because the Roosevelt administration was pushing the limits of what a neutral nation can do for pleasant nations with out turning into a warring celebration.
In January of 1941, Roosevelt gave his annual State of the Union speech to Congress. He appeared to organize the nation for potential intervention – each on behalf of allies overseas and for the preservation of American democracy:
“The longer term and the security of our nation and of our democracy are overwhelmingly concerned in occasions far past our borders. Armed protection of democratic existence is now being gallantly waged in 4 continents. If that protection fails, all of the inhabitants and all of the assets of Europe, and Asia, and Africa and Australasia might be dominated by conquerors. In occasions like these it’s immature – and by the way, unfaithful – for anyone to brag that an unprepared America, single-handed, and with one hand tied behind its again, can maintain off the entire world.”
When the Japanese attacked Hawaii in 1941 and Hitler declared war on the U.S., America shortly entered World Battle II in an alliance with Britain, the Free French and others.
All through the battle, the Allies labored collectively on issues massive and small. They defeated Germany in three and half years and Japan in lower than 4.
As World Battle II ended, the wartime alliance produced two longer-term partnerships constructed on the understanding that working collectively had produced a strong and efficient counter to fascism.

Foreign Policy In Focus
Postwar alliances
The primary of those alliances is the North Atlantic Treaty Organization, or NATO. The unique members had been the U.S., Canada, Britain, France and others of the wartime Allies. There are actually 32 members, together with Poland, Hungary and Turkey.
The aims of NATO had been to maintain peace in Europe and comprise the rising Communist menace from the Soviet Union. NATO’s supporters really feel that, on condition that wars within the former Yugoslavia within the Nineteen Nineties and within the Ukraine at the moment are the one main conflicts in Europe in 80 years, the alliance has met its goals well. And NATO troops went to Afghanistan together with the U.S. navy after 9/11.
The opposite establishment created by the wartime Allies is the United Nations.
The U.N. is many issues – a humanitarian assist group, a discussion board for international locations to boost their points and a supply of worldwide regulation.
Nonetheless, additionally it is an alliance. The U.N. Security Council on several occasions authorized the usage of power by members, similar to within the first Gulf Battle towards Iraq. And it has the facility to ship peacekeeping troops to battle areas underneath the U.N. flag.
Different U.S. allies with treaties or designations by Congress include Australia, New Zealand, Japan, Israel, three South American international locations and 6 within the Center East.
Most of the identical international locations additionally created establishments such because the World Financial institution, the Worldwide Financial Fund, the Group of American States and the European Union. The U.S. belongs to all of those besides the European Union. Throughout my 35-year diplomatic career, I labored with all of those establishments, notably in efforts to stabilize Africa. They keep the peace and support development efforts with loans and grants.
Admirers of this postwar liberal worldwide order level to the restricted variety of major armed conflicts during the past 80 years, the globalized financial system and worldwide cooperation on essential issues such as disease control and fighting terrorism.
Detractors level to this technique’s incapability to cease some very lethal conflicts, similar to Vietnam or Ukraine, and the big populations that haven’t finished nicely underneath globalization as evidence of its flaws.
The world would look dramatically completely different with out the Allies’ victories within the two World Wars, the steady worldwide financial system and NATO’s and the U.N.’s maintaining the world comparatively peaceable.
However the worth of allies to People, even after they profit from alliances, seems to have shifted between George Washington’s perspective – keep away from them – and that of Franklin D. Roosevelt – go all in … finally.
That is an up to date model of an article originally published on Feb. 20, 2025.
