What kind of war is called the beginning of the transition of the fascist states of Europe to direct armed aggression?

In this case, perhaps, there is a conflict in Albania or in Ethiopia. In both cases, Italy was the aggressor. She strove to expand her sphere of influence, to capture new states. Therefore, she planned and carried out aggression against those territories that could not provide direct resistance. Also (if we mean Germany) such a conflict can be the seizure of Czechoslovakia. However, there were no direct armed clashes. German troops simply reached Prague without fire from the Czechoslovak units.
