The debate on defense spending is heating up ahead of a summit of U.S. President Donald Trump and his NATO counterparts in the Netherlands on June 24-25. It’s a high-level gathering that will set the course for future European security, including that of Ukraine.

At talks in Antalya, Turkey, NATO Secretary-General Mark Rutte said that more investment and military equipment are needed to deal with the threat posed by Russia and terrorism.

ANTALYA, Turkey - Germany on Thursday backed U.S. President Donald Trump's demand to more than double NATO's defence spending target to 5% of GDP, as Washington urged countries to eliminate any \"weak links\" in the alliance caused by a lack of military investment.
