Warsaw is backing Donald Trump’s demand for Nato countries to spend 5 per cent of GDP on defence even if it will take 10 years for the alliance’s laggards to reach the target, says the Polish defence minister.

Poland supports the demand of elected President Donald Trump for NATO countries to increase defense spending to 5% of GDP. However, Warsaw believes this will only happen in 10 years, states Polish Defense Minister Władysław Kosiniak-Kamysz in an interview with the Financial Times.

Ralf Stegner, a member of Germany's Social Democratic Party, called Trump's comments "delusional and truly insane." Poland has backed Trump's demand.

Poland is backing Donald Trump’s call to NATO countries to spend 5 percent of their GDP on defense. Trump’s call for alliance members to more than double the target for defense budgets has prompted a mixed reaction among Europe’s cash-strapped governments.

However, a new target is likely to be agreed at a NATO summit in The Hague in June, spurred by fears that Russia may attack a NATO country after Ukraine and by Trump’s exhortations, officials said. The key open questions are what that new target will be and whether it will be enough to satisfy Trump.

U.S. President-elect Donald Trump said on Jan. 7 that NATO should raise its defense spending benchmark from 2% of GDP to 5%, echoing his earlier calls for Europe to spend more on its security.
