Explanation:

• First question: In 1941, the U.S. imposed a complete oil embargo on Japan. Japan, highly dependent on oil imports for its military and industrial operations, saw this as a severe threat. Without oil, its war machine (especially in its ongoing campaigns in China and Southeast Asia ambitions) would grind to a halt. This economic pressure was a direct factor that led Japan to consider a preemptive strike (Pearl Harbor) to secure oil - rich regions in Southeast Asia. Signing a pact with Britain was more about broader Allied cooperation, closing immigration was a long - standing (and racist) policy not directly tied to Pearl Harbor, and deploying forces to the Philippines was a more general military posture but not the direct economic trigger like the embargo.
• Second question: Both the U.S. and Canadian (and other countries with Japanese - descent populations in some cases) governments used the justification of national security and fears of espionage. In the context of wartime (especially after Pearl Harbor), there was a climate of xenophobia. Despite a lack of evidence of widespread disloyalty among Japanese - citizens, the argument was made that they might (as a group) spy for Japan. Economic competition was more of a pre - war undercurrent in some areas (like California agriculture), diplomatic pressure was not the main reason, and labor union pressure was a minor factor compared to the national security rhetoric.

Answer:

• First question: Imposing a complete oil embargo on Japan.
• Second question: National security and fears of espionage.
