The effects are probably more profound that just losing allies. It also could crash financial market, and tech wise would force EU to develop it's own industry, like baidu or yandex
I included the economic disaster in my list. I just felt that I needed to explain why I considered it a military disaster even though the US could likely "win" Greenland. It would lose Europe and the ability to project military power through Europe. This impacts the ability to project power in Africa and the Middle East. It'll lead to a cascading military failure which leads to lots of other problems including further economic problems.
