Aggression

Unjustified planned, threatened, or carried out use of force by one nation against another.

The key word in the definition of aggression is "unjustified"—that is, in violation of International Law, treaties, or agreements. It was the basic charge leveled against Nazi Germany at the Nuremberg Trials in 1946.
