"EU foreign policy chief Kaja Kallas described the US as an 'indispensable ally' but admitted that relations were 'not as good as they used to be', as she met with German Defence Minister Boris Pistorius in Berlin on Tuesday. "I also want to touch on the state of transatlantic relations, which has been much of a subject recently," she said. "The United States is an indispensable ally, but it's also clear that our relations are not as good as they used to be. In every alliance, there are moments of open disagreement, but Europe will not junk 80 years of transatlantic relations. From Gaza to the fight against ISIS to China's coercive economic practises, Europe and the US are stronger when we act together." The past days and weeks have seen rows with the US over Greenland, with Donald Trump pledging to take control of it 'one way or another'. In recent days, the UK has suggested deploying NATO troops to the Danish territory, which some media reports have suggested was about 'easing Trump's security fears' and others have claimed to be about 'deterring' the US president. Earlier, Danish PM Mette Fredriksen stated: "It has not been easy to stand up against completely unacceptable pressure from our closest allies through a generation, but much simultaneously suggests that the hardest part now lies ahead of us.""
