Spain has rejected a U.S.-backed proposal for NATO members to raise defense spending to 5% of GDP, becoming the first alliance country to oppose the plan, Reuters reported on June 19.

The rejection adds pressure to the transatlantic debate ahead of the NATO summit in The Hague on June 24–25, which has beenreduced to a single session focused on defense spending and alliance capabilities.  

In a letter to NATO Secretary General Mark Rutte, Spanish Prime Minister Pedro Sanchez called the proposed target "unreasonable" and warned it would undermine broader European efforts to build an integrated defense ecosystem.

"Committing to a 5% target would not only be unreasonable, but also counterproductive," Sanchez wrote, arguing it would "move Spain further away from optimal spending."

Spain estimates that its armed forces require spending equal to 2.1% of GDP to meet national military objectives, below the U.S.-endorsed threshold but above NATO's 2% benchmark.

U.S. President Donald Trump has repeatedly accused NATO members of underfunding their militaries, pushing for raising defense spending benchmark to 5% of GDP.

While no other NATO members have formally rejected the proposal, most have remained noncommittal. Poland, the Netherlands, and Sweden have expressed willingness to consider the 5% target.

In 2024, only 23 alliance members met the 2% target, according to NATO estimates. Poland was ahead of all members with 4.12% of GDP allocated to defense, followed by Estonia (3.43%) and the U.S. (3.38%).

Rutte said on June 17 that all NATO countries are on track to meet the 2% threshold in 2025.

Spain, governed by a Socialist-led coalition, maintains a sharply different defense posture than the U.S. administration.

While Madrid supports Ukraine, it has taken a more cautious stance on the Middle East, including distancing itself from U.S. policy on Israel.

Diplomacy in crisis: G7 letdowns reveal limits to Western solidarity on Ukraine

KANANASKIS, Canada — The Group of Seven (G7) Leaders’ Summit ended on June 17 with no joint statement in support of Ukraine, no commitments to provide desperately needed U.S. weapons, and no meeting between President Volodymyr Zelensky and U.S. President Donald Trump. The Ukrainian delegation headed into the summit,

Failure to provide stronger military and financial support for Ukraine could leave Europe vulnerable to growing Russian influence, meaning Europeans might have to "start learning Russian," the EU's top diplomat, Kaja Kallas, said, the Guardian reported on June 17.

"We know that Russia responds to strength and nothing else," Kallas said. She called Ukraine "Europe's first line of defense" and emphasized the need for continued sanctions against Russia and more aid to Kyiv.

The comments come as Russian forces are intensifying their attacks on Ukrainian cities and the Kremlin continues to reject a push by Kyiv and its Western allies for an unconditional ceasefire.

"To quote my friend, NATO Secretary General Mark Rutte: if we don’t help Ukraine further, we should all start learning Russian," Kallas said.

Kallas cited a sharp increase in Russia's military spending, noting that Moscow is now allocating more money to defense than the EU combined, and more than its own health care, education, and social policies put together.

"This is a long-term plan for a long-term aggression," she said.

In light of this, Kallas urged governments to adopt NATO's new target of spending 5% of GDP on defense, warning of Russia's hybrid warfare tactics, including airspace violations, attacks on critical infrastructure, and covert sabotage operations within EU borders.

The 5% defense spending target is expected to be formally adopted during the upcoming NATO summit, which will take place on June 24 and 25 in The Hague. U.S. President Donald Trump has insisted that the European allies increase their defense budgets.

Earlier, Kallas said Russian President Vladimir Putin "cannot be trusted" to mediate peace while continuing to bomb Ukrainian cities and civilians, as Moscow suggested to mediate negotiations between Israel and Iran amid growing escalation.

"Clearly, President Putin is not somebody who can talk about peace while we see actions like this," she said during a June 17 briefing, after a massive Russian missile and drone strike on Kyiv killed at least 28 people and wounded over 130.

Kallas also reiterated her call for the EU to move forward with tightening the oil price cap on Russian exports, even without U.S. backing. She warned that the ongoing Israel-Iran crisis could cause oil prices to spike, boosting Russia's war revenues.

The EU is currently preparing its 18th sanctions package against Moscow, targeting energy, defense, and banking sectors. The 17th round of sanctions came into effect in May.

Putin says he’s ready to meet Zelensky if West ‘stops pushing’ Ukraine to fight

Russia wants to end the war in Ukraine “as soon as possible,” preferably through peaceful means, and is ready to continue negotiations — provided that Kyiv and its Western allies are willing to engage, Vladimir Putin said.
