WASHINGTON, July 13. /TASS/. NATO members have achieved "great success" during their latest summit, US President Donald Trump has said in his Twitter.

"Great success today at NATO! Billions of additional dollars paid by [NATO] members since my election [to the post of US president]," he said on Thursday.

Trump has repeatedly criticized NATO members for not spending enough on NATO collective defense. He demanded that all members increase their defense spending to 2% of GDP. During his speech at the latest summit, Trump suggested further increasing the threshold to four percent.

At present, only eight NATO members spend more than 2% of their GDP on their defense. The US military budget stands at approximately 3.58% GDP.
