I don't think so.
I know that the British invaded Iceland to keep it from falling into the hands of the Germans during WWII, so I suppose there could be some type of world war scenario under which the US would have to act to keep Greenland from falling.
But, I highly doubt Jimbasil has thought about it as much as I have typed. He's just emoting because the Dems wanted trans story hours for children in public libraries more than they wanted to win the presidency. It was a funny question, because I don't think he thinks Trump would do that, and I don't think Trump supporters think he will do that, absent an active threat from a major power. Then again, I was surprised when we invaded Granada and Panama, so I guess shit happens.
