It is clear that in those 'virtual' negotiations, the participating sides were the US, Russia and China. The EU, including Denmark, the country whose territory Greenland is, was not. India neither. The old rule that if you are not part of the negotiations, you are likely a subject to the decisions, holds true. Possible future steps would include annexation of Greenland, as indicated by Trump on multiple occasions, including also in interviews after the Venezuela takeover. This would achieve another objective – to weaken the EU further, as no EU state will likely challenge the US if the annexation happens.
