Deploying troops to Greenland right now would be solely aimed at seizing Greenland by force and would be a major international incident against the US's most important military allies. Deploying troops to Minnesota would be a domestic show of force that would have minimal impact, as they are incapable of seizing Minnesota for the US as it is already a US territory, so they would be used to guard public buildings (and would basically just sit around doing nothing all day).
