Please read OP, I've explained it there. As for consequences, the first major one was Denmark activating the 1952 directive. This orders all Danish military personnel to open fire at US the moment they see their forces approaching without needing any secondary orders at all. That is the end of NATO and increases the isolation of USA one step further as a pariah state with a rogue regime.
I read your OP and I see just biased opinion. IMO, I don't see that these things is going to change things globally and how other countries follow or not follow international law. I don't support what Trump is doing and in general, there is lot of stupid things coming from US administration. But no, there won't be new world order.
About Grenland, don't forget that they already have US military bases there. I don't believe that Grenland will be taken, but if it will happen - any shots won't be fired.
