Montenegro has officially become the 29th member of NATO after a process that saw a failed coup attempt believed to be supported by Russia, and U.S. senators hurling invectives.
The tiny Balkan nation on the Adriatic Sea officially joined the alliance in a ceremony Monday at the State Department, where officials hailed the strength of the alliance.
“Montenegro’s accession sends a strong message of strength to the region and makes clear to our allies that the United States remains as committed as ever to the principal of collective defense as enshrined in Article 5 of the Washington Treaty,” Thomas Shannon, undersecretary of State, said at the ceremony.
The growth of NATO comes as President Trump’s commitment to the alliance continues to be called into question.

Administration officials have since said Trump is committed to Article 5, but Trump has yet to say so himself.
Trump also caused a stir when he appeared to push aside the prime minister of Montenegro so that he could be in the front of a photo of NATO leaders.
In March, the Senate approved Montenegro’s bid to join the alliance in a 97-2 vote.
Despite the strong support, the vote caused some turmoil in the chamber. Sen. Rand Paul (R-Ky.) had earlier blocked a vote on the treaty, arguing that allowing the country into the alliance would add to America’s military burden.
Paul’s move prompted Sen. John McCain (R-Ariz.) to lament that his colleague “is now working for [Russian President] Vladimir Putin.”
Monday’s ceremony is the culmination of seven years of work for Montenegro.
The process endured a coup attempt in October 2016 that Montenegrin and U.S. officials have said was sponsored by Russia.
In Monday’s ceremony, Shannon commended Montenegro for joining the alliance in the face of “concerted foreign pressure.”
He also highlighted Montenegro’s commitment to spending, saying it will spend 1.7 percent of its gross domestic product on defense and envisions spending 2 percent by 2024.
Montenegro has also contributed to the wars in Afghanistan and against the Islamic State in Iraq and Syria, Shannon added.
NATO Secretary-General Jens Stoltenberg, who was at the ceremony, said Montenegro’s accession sends a message to other countries hoping to join the alliance.
“Montenegro’s accession sends a signal to other states that seek membership,” he said, “that if a country truly reforms, if it promotes democracy, strengthens the rule of law, modernizes its armed forces and contributes to our collective defense, it too can join the alliance.”
Montenegro’s Prime Minister Duško Marković thanked the United States for its “staunch and continuous support” for his country’s NATO membership and pledged that his country will be a “strong advocate and partner” for NATO’s efforts in the region.
“I firmly believe that this is a historic day for NATO,” he said at the ceremony. “Facing the new and grave challenges, the alliance’s admitting the 29th member show increasingly that the open-door policy is alive and that it works well as a beacon of hope to all of those who want to share its values and standards.”
