Watching can be more casual and may not involve as much intentional focus as observing. **

Wallenstein's approach to warfare was characterized by aggressive tactics and a focus on maintaining and expanding his military influence, making this motto a fitting representation of his approach to the conflict. **

The Second World War turned from a European war into a world war primarily due to the expansionist policies of Nazi Germany and Japan. Germany's invasion of Poland in 1939 prompted Britain and France to declare war, drawing in their colonies and allies from around the world. Japan's aggressive actions in Asia, such as the invasion of China and the attack on Pearl Harbor in 1941, further escalated the conflict by involving countries in the Pacific and Southeast Asia. The alliances formed between the Axis powers and the Allied powers also contributed to the global nature of the war, as countries from different regions joined the fight on either side. **

Both sides used Korea as a proxy to advance their own interests and ideologies without engaging in direct conflict with each other. **
