If we owned or just came to a agreement with Greenland, it would go a very long way to preventing China and Russia from attacking us.
Let me word this in terms that Democrats will understand. Xi Zinping and Vladimir Putin hate LGBT+, African-Americans and people who illegally immigrated to America. There is a very strong possibility that they might use their white and white-adjacent privilege to launch nukes to target LGBT+, African-Americans and Illegal Immigrants. If we could own or, at least, have an agreement with Greenland we could put an end to racism.
