WASHINGTON, July 6 — Donald Trump’s relationship with NATO has never been a straightforward one. Under the hood, the technical reality of alliance commitments often clashed with the former president’s transactional view of international partnerships. During his single term in the White House, from January 20, 2017, to January 20, 2021, Trump repeatedly criticised NATO member states for insufficient defence spending.
The detail that matters here is that he reportedly considered withdrawing the United States from the alliance altogether — a move that would have fundamentally altered the post-war security architecture of Europe. In 2018, Trump caused particular controversy by questioning whether he would defend Montenegro, a NATO member, under Article 5 — the collective defence clause that is the alliance’s core.
That moment crystallised for many allies the unpredictability they faced. Trump’s history with Ukraine is equally fraught. In 2019, he was impeached on charges of abuse of power and obstruction of Congress.
The impeachment stemmed from his pressure on Ukrainian President Volodymyr Zelensky to investigate Joe Biden, which led to a temporary freeze on $391 million in military aid. That figure — $391 million — represents the tangible cost of the political standoff.
Now, as the presumptive 2024 Republican nominee, Trump has made a striking claim. He has stated he could end the Russia-Ukraine war within 24 hours if elected. That assertion has raised concerns among allies about continued U.S. support for Ukraine under a potential second Trump administration.
The technical reality is that ending a war of this scale in 24 hours would require either a dramatic concession from Kyiv or a complete withdrawal of American backing. Neither scenario aligns with current NATO policy or the expressed interests of most member states. As ever, the question is whether Trump’s rhetoric will translate into policy.
His track record suggests the answer may not be straightforward. For now, European allies are watching closely, calculating what a second Trump term might mean for the alliance’s future.
