Question

When an attack by hostile aircraft is considered probable, imminent, or taking place upon the continental United States or Canada, which declaration is declared?

Answer 1

In the event of a probable, imminent, or ongoing attack by hostile aircraft on the continental United States or Canada, a state of war is declared as a response to ensure national defense. This was evident during significant events such as the attack on Pearl Harbor by Japan in 1941 and subsequent declarations of war.

Step-by-step explanation:

The declaration that is declared when there is a probable, imminent, or ongoing attack by hostile aircraft upon the continental United States or Canada is a state of war. This was the case during specific events such as the attack on Pearl Harbor by Japan on December 7, 1941, which led to a declaration of war between the United States and Japan. Additionally, during World War II, the United States declared war on Germany and Italy after their respective declarations of war against the United States.
