Trump's erratic approach to US military deployment has European allies uncertain over their defence strategies [File: Jonathan Ernst/Reuters]By Al Jazeera Staff and News AgenciesPublished On 22 May 202622 May 2026
United States President Donald Trump has announced plans to deploy an additional 5,000 troops to Poland.
Trump announced the surprise deployment on social media late on Thursday, citing his friendship with right-wing Polish President Karol Nawrocki.
The move came days after a planned deployment to Poland was apparently scrapped and will deepen uncertainty surrounding the Trump administration’s approach to NATO allies and its long-term commitment to maintaining a military presence in Europe. It leaves European partners increasingly unclear about which areas they should prioritise as they formulate defence strategies.
“Based on the successful Election of the now President of Poland, Karol Nawrocki, who I was proud to Endorse, and our relationship with him, I am pleased to announce that the United States will be sending an additional 5,000 Troops to Poland,” Trump wrote.
“Good alliances are those based on cooperation, mutual respect, and a commitment to our shared security,” he wrote on Thursday evening.
Polish Foreign Minister Radek Sikorski also welcomed the news on Friday, saying it ensures that “the presence of American troops in Poland will be maintained more or less at previous levels”.
The announced deployment is a sudden about-face from US declarations of plans to reduce military support to Europe under Trump’s “America First” doctrine.
The US president has for years been lambasting European NATO partners for failing to spend enough on defence. His opprobrium has risen in recent weeks as European states have criticised the US-Israeli war on Iran and refused to join the conflict.
The Pentagon abruptly announced a week ago that it was scrapping the planned deployment of 4,000 troops to Poland.
Earlier this month, Trump announced he was withdrawing 5,000 troops from Germany following a spat with Chancellor Friedrich Merz, who said Washington had been “humiliated” by Iranian negotiators.
The US president later said that he would be “cutting a lot further than 5,000”.
Polish officials have noted that Warsaw pays significant sums towards the cost of US troop deployments. The suggestion of a pullback has caused concern over security in Poland and elsewhere in Europe, as Russia’s war on neighbouring Ukraine continues, with the Trump administration largely ceasing efforts to mediate a ceasefire.
European states report that they are getting to grips with the need to replace US defence capabilities, albeit slowly. However, sources suggest that the erratic policies emerging from the White House are creating confusion over which elements should be prioritised.
“It is confusing indeed, and not always easy to navigate,” Swedish Foreign Minister Maria Malmer Stenergard told reporters ahead of hosting a meeting of NATO foreign ministers on Friday, which will be attended by US Secretary of State Marco Rubio.
US defence officials are also confused, according to the AP news agency.
“We just spent the better part of two weeks reacting to the first announcement. We don’t know what this means either,” said one official.
The US president has lashed out at fellow NATO members in recent months for failing to support the US-Israeli war on Iran, suggesting Washington could withdraw from the military alliance as a result.
State Department spokesperson Tommy Pigott said Rubio would discuss the need for NATO allies to increase defence spending and shoulder greater responsibility at Friday’s meeting of NATO foreign ministers.
NATO Secretary-General Mark Rutte, who has worked hard in recent months to attempt to soothe the US president’s displeasure with his alliance peers, welcomed Trump’s deployment to Poland and cautioned that Europe must become less reliant on the US.
Rubio said before meeting his NATO counterparts in Sweden: “Like any alliance, it has to be good for everyone who’s involved. There has to be a clear understanding of what the expectations are.”
He also suggested, however, that the meeting is likely to prove less than comfortable.
“The president’s views, frankly disappointment, at some of our NATO allies and their response to our operations in the Middle East – they’re well documented – that will have to be addressed,” he insisted, before adding “that won’t be solved or addressed today”.
While Rubio meets with NATO counterparts, senior Pentagon officials will brief partners at the alliance’s headquarters in Brussels about Washington’s commitment to European defence.
On Tuesday, the Pentagon announced it plans to reduce the number of combat brigades based in Europe from four to three.
Many of Washington’s allies in Europe remain frustrated with Trump’s handling of the war with Iran, which has damaged their economies and prompted some European leaders to question the reliability of the US.
European NATO countries also remain concerned about Trump’s threats to annex Greenland, which is an autonomous territory of the Kingdom of Denmark, a NATO ally.
It remains unclear whether the deployment to Poland announced on Thursday includes the same soldiers as those the Pentagon said would no longer be deployed to the Central European country, or if they will include redeployments from Germany.
