US Defence Secretary Pete Hegseth said Thursday that America's allies in Europe must take the lead on the defence of their own continent and help turn NATO into "a read hard-line military alliance." At a meeting of NATO defence ministers, Hegseth called for a reboot of the 32-nation organisation to turn it into a "NATO 3.0" capable of deterring any threat. His remarks came a few weeks after the United States told its allies that it would no longer supply certain warships and aircraft if one of them comes under attack. European allies and Canada are trying to work out how to plug the gaps.
