Could UK troops defend Greenland and does it even need defending?

The environment will kill you far quicker than any enemy would, so it is a real challenge, and when you talk about logistics and actually keeping forces supplied, be it by ship or helicopter, again it just makes it far more challenging. I think the benefit from a NATO perspective is that quite a lot of NATO members are not just Arctic trained, that's all they know...The military balance in the Arctic now is looking far better for NATO now that it did in 2021."
