Spanish authorities and NATO officials are not taking seriously U.S. President Donald Trump’s threats to punish Madrid for failing to increase its military spending, according to Politico, citing an alliance representative.

“The threat is not taken seriously within military circles. The Spaniards are responding calmly,” the source told the publication.

Politico notes that Trump’s rhetoric toward Spain has grown harsher after Madrid refused to increase defense spending, which conflicts with the American leader’s plan to reduce Europe’s dependence on U.S. military power. White House Deputy Press Secretary Anna Kelley told the outlet that the U.S. president is still “considering the economic consequences of the Spanish authorities’ decision.” She added, “While all other NATO allies have agreed to raise defense spending to 5% of GDP, Spain was the only country to refuse.”

On October 14, President Trump announced the possibility of imposing import tariffs in bilateral trade with Spain due to disagreements over NATO spending. Earlier, the U.S. leader had also suggested that the kingdom might need to be excluded from NATO because its military spending was deemed insufficient by Washington.
