Can't promise that US will stay in NATO: Norway Finance Minister

Amid US President Donald Trump's repeated threat to annex Greenland, Norway's Finance Minister and ex-NATO chief Jens Stoltenberg said, "I can't promise that...US will stay in NATO. No one can." "We must do everything we can to reduce...risk of...US leaving, and that we ourselves are in the best possible position to deal with it if it happens," Stoltenberg added.
