Greenland, no. But to act like the Democrats aren't involved in imperialism, plunder, and genocide in other places is absurd. I'm not willing to sacrifice those other countries and people for the sake of Greenland, or for my own sake, or for the sake of my neighbors.
In my view, genocide is completely off the table in the range of solutions I'm willing to consider. I'll oppose the right by whatever means are available to me, but that's simply not an option.
If you want to argue that I have a moral responsibility to aid other countries and ensure their safety and security, maybe to some extent that's true. But any such positive moral duty certainly does not outweigh my negative moral duty to not actively fuck with other countries, to not be the danger I'm supposed to be preventing. "First, do no harm." If protecting Finland requires me to support the wanton slaughter of innocent Palestinians, then you're on your own. If protecting Palestinians meant actively supporting the wanton slaughter of Finns, then I would say the same thing.
