If Europe wants North America to intervene in Europe's territorial disputes, then Europe should allow North America to have dominion over North America.

It's hypocritical for Europe to claim North American territory, and then claim we should be concerned about a European nation claiming European territory.

Russia and Ukraine are both on the same continent. They're neighbors. That's a much tougher decision than whether a European nation should control Greenland... that's not even on the same hemisphere.
