Countries With Whom the US Has No Diplomatic Relations

The United States maintains embassies around the world. It does not run one in three. As of 2026, the only United Nations member states with no formal diplomatic relations with Washington are Bhutan, Iran, and North Korea. For years the list carried a fourth name, Syria, but that changed in 2025. And the reasons the remaining three are missing from the map could not be more different. One is an old enemy. One has never been an enemy at all. One simply never picked up the phone.

Bhutan

Start with the strangest case. Bhutan is not on this list because of any quarrel. The small Himalayan kingdom never established formal diplomatic relations with the United States, and it has never established them with any of the five permanent members of the UN Security Council either. By every account, the two countries are on warm terms.

Bhutan simply runs a deliberately small foreign policy. It keeps formal ties with only a few dozen countries and has long coordinated much of its outside business through neighboring India. Its contacts with Washington run through Bhutan's permanent mission to the United Nations in New York, while the United States covers Bhutan from its embassy in New Delhi. There is no embassy in Thimphu and never has been. The absence is a quirk of Bhutanese policy, not a snub, and officials on both sides stay in touch without one.

Iran

Iran is the opposite story. The two countries kept relations for nearly a century before a single crisis ended them. In November 1979, months after the revolution toppled the US-backed shah, militants stormed the US Embassy in Tehran and seized 52 Americans. They held them for 444 days. Washington cut diplomatic ties in April 1980, and they have never been restored.

The hostages walked free in January 1981, minutes after Ronald Reagan was sworn in, but the rupture held. Switzerland has served as the US protecting power in Iran ever since, running an American interests section out of its embassy in Tehran and handling the consular work an embassy normally would.

None of that has kept the two apart. For all the decades without an embassy, Washington and Tehran have stayed locked together, and in 2026 the standoff turned into open war. In late February, the United States joined Israel in a wave of airstrikes on Iran, aimed at its nuclear and missile programs and at the government itself. Iran's supreme leader, Ali Khamenei, was killed. Iran fired back at Israel and at US bases around the region and closed the Strait of Hormuz, choking off a major share of the world's oil and gas. The fighting ran more than five weeks before a ceasefire took hold in April, brokered not by either government but by Pakistan. Months of mediated talks followed, and in June the two sides reached a peace deal that ended the war and reopened the Strait of Hormuz to shipping, with a permanent settlement still to be negotiated. Two governments with no embassies and no ambassadors had fought a war and made peace, start to finish, through other countries' diplomats.

North Korea

North Korea has never had diplomatic relations with the United States. Not strained, not severed. Never established. The two have been enemies since the Korean War, which ended in 1953 with an armistice and no peace treaty, so on paper they remain at war. Pyongyang is one of only two Asian capitals that has never hosted an American embassy. The other is Thimphu.

Sweden fills the gap. Its embassy in Pyongyang has acted as the US protecting power for decades, looking after American consular matters in a country where Washington keeps no presence of its own. The Trump-Kim summits of 2018 and 2019 produced handshakes, a stroll across the DMZ, and a wall of headlines, but the Hanoi meeting broke up without a deal, and no embassy or formal ties followed. The relationship remains exactly what it has always been, which is none.

The Name That Just Came Off the List

For more than a decade, Syria was the fourth country here. The US suspended relations in 2012 during the Syrian civil war and shut down the operations of the Syrian embassy in Washington in 2014. Then the Assad government fell in December 2024. A new government under Ahmed al-Sharaa took power, and in September 2025 the United States reopened relations with Syria. That November, al-Sharaa became the first Syrian head of state to visit the White House since Syria's independence in 1946, and Washington authorized Syria to reopen its embassy. Syria is off the list. It is the clearest possible reminder that this map is not fixed.

The Gray Areas

The clean count of three hides some messier cases. The United States has no functioning embassy in Afghanistan. It closed the Kabul mission in 2021 when the Taliban took over and does not recognize the Taliban as the country's legitimate government, even though it never formally severed ties with the Afghan state itself. Venezuela is a similar knot. The US withdrew its diplomats from Caracas in 2019, and relations have only grown more hostile since. Recognition can be the whole problem, too. The United States does not recognize the State of Palestine, and it deals with Taiwan through an unofficial institute rather than an embassy while treating the island as a de facto partner. None of these fit cleanly into a yes-or-no column, which is why the headline number is always "three" with an asterisk.

Cuba is the gray area that runs the other way. Plenty of Americans assume Havana belongs on the no-relations list, given the embargo and more than sixty years of hostility, but it does not. The United States and Cuba severed ties in 1961 and restored them in 2015, when both countries reopened embassies in each other's capitals. What makes the case gray is everything stacked on top of those embassies: the decades-old trade embargo, tight limits on travel and money transfers, a partial drawdown of the Havana embassy after the unexplained health incidents reported among US diplomats there in 2017, and Cuba's return to the US list of state sponsors of terrorism, where the second Trump administration placed it again in 2025. On paper the relationship is whole. In practice it barely functions.

What "No Relations" Actually Means

So what does it mean for two countries to have no diplomatic relations? Mostly it means no embassy and no ambassador. It does not mean no contact. A protecting power steps in, messages still move through third parties, and in Bhutan's case the two sides are openly friendly. Cutting relations is a diplomatic signal, not a sealed border. The United States has used the move to register outrage, as with Iran, and watched it dissolve when circumstances change, as with Syria. The list is short. It is not permanent. And as Syria just demonstrated, a name can drop off it in a matter of months.
