NATO's target of spending 2% of members' GDP on defense is insufficient, the US president said

Rome needs to spend more on its military because NATO's 2% target is no longer enough, US President Donald Trump has told Italian Prime Minister Giorgia Meloni.

While the US is the biggest financial contributor to the alliance, Trump has long insisted that European member states must boost their own defense. The debate over burden-sharing between the allies further complicates the Trump administration's strained relations with Europe.

During a joint press conference in Washington on Thursday, Meloni stated that "Italy is going to the next summit of NATO, announcing that it will raise [defense spending] to 2%, and that's also progressed."

"It will go up," Trump interjected. When asked by a reporter if the 2% target was sufficient, the US president replied, "It's never enough."

Last year, Italy's defense budget stood at 1.49% of GDP - one of the lowest in NATO. Meloni has been advocating for some time to reclassify expenditure on border patrols and coast guards as military spending.

In January, Trump accused European countries of taking advantage of the US and argued that NATO members should spend at least 5% of their GDP on defense. Last year, twenty-three of the 32 members hit the 2% target set by NATO in 2014, according to the bloc's own estimate cited by the BBC. The US spends around 3.5% of its GDP on defense and is NATO's biggest overall contributor.

Italian Defense Minister Guido Crosetto told the newspaper La Stampa this week that it was "unthinkable" to assume that all European nations would slash social programs to fulfill Trump's 5% demand. "European countries can't touch welfare and social achievements," he said.

Last week, Trump said he would not rule out pulling some or all of the 84,000 US troops currently stationed in Europe. "We pay for the military in Europe. We don't get reimbursed by much," Trump told reporters at the White House.

The New York Times reported on Monday that the US could slash "almost all funding" for international organizations, including the United Nations and NATO.
