No one is calling for war, but it's not like that documented history happened in this century. Greenland had been part of Denmark since the vikings. Surely we can get past the history and talk in today's terms. The people of Greenland have a voice in Danish politics and both the people and politicians said NO to wanting to have US rule them and YES to stay with Denmark.

So yes, defending Greenland becomes a case of helping a people stay free and not invaded, no matter the enemy.

It's silly to say "well we have no chance against" because then you can end that with China, Russia or even India.
