I don’t have your specific article or images, so below are two complete C-E-R examples (one arguing “No” and one arguing “Yes”) you can use or adapt. Pick the one that matches the evidence in your materials and your view.
Option A — Claim (No: not justified)
Claim
- No — Japan was not justified in attacking Pearl Harbor for oil.
Evidence (bullets you can match to your article/images)
- The United States and its allies imposed economic sanctions and an oil embargo, but also engaged in diplomatic negotiations with Japan in 1941.
- The U.S. froze Japanese assets and restricted oil exports, creating severe economic pressure on Japan.
- Japan launched a surprise attack on Pearl Harbor on December 7, 1941, without a formal declaration of war.
- The attack targeted military personnel and ships, caused heavy loss of life (over 2,400 Americans killed) and sank or damaged numerous vessels and aircraft.
- Japan had alternatives: continued negotiations, withdrawal from some Chinese territories, or seeking resources through diplomacy rather than attacking a neutral nation’s fleet.
- The attack violated international norms and treaties against unprovoked aggression and surprise attacks.
Reasoning (one-paragraph answer using definition of “justify”)
- To justify an action means to show it was reasonable, necessary, and proportionate under the circumstances. Although Japan faced a real oil shortage because of embargoes, attacking Pearl Harbor was not a necessary or proportionate response. The U.S. oil restrictions were a coercive economic policy, but Japan still had diplomatic options and could have pursued less violent ways to secure resources. The surprise attack deliberately targeted lives and property and violated international norms, and it triggered a much wider war. Because the attack was avoidable and excessively violent relative to the problem, Japan’s action cannot be justified as a morally or legally acceptable response to an oil embargo.
Option B — Claim (Yes: justified)
Claim
- Yes — Japan was justified in attacking Pearl Harbor to secure access to oil (from the Japanese government’s survival perspective).
Evidence (bullets you can match to your article/images)
- Japan relied heavily on imported oil and had limited domestic energy resources; embargoes threatened Japan’s navy, military operations, industry, and national survival.
- After Japan’s expansion in China and Indochina, the U.S., Britain, and the Netherlands imposed sanctions and cutoff of oil supplies.
- The U.S. froze Japanese assets and made continued access to oil contingent on Japan withdrawing from China — a demand Japan was unwilling to meet.
- Japanese leaders believed the United States would use its Pacific Fleet to block Japan’s seizure of oil-rich territories in Southeast Asia, so crippling that fleet at Pearl Harbor was seen as a preemptive military necessity.
- The attack aimed to buy time to secure resources and strengthen Japan’s position before the United States could respond.
Reasoning (one-paragraph answer using definition of “justify”)
- To justify an action is to show it was necessary and reasonable given the circumstances. From the Japanese leadership’s perspective, the U.S.-led oil embargo created an existential crisis: without oil, Japan could not feed its population, run its economy, or maintain its military. With diplomatic talks stalled and the U.S. Pacific Fleet positioned to block Japanese moves in Southeast Asia, a preemptive strike at Pearl Harbor was seen as a necessary military step to protect national survival and secure access to vital resources. Under that reasoning, the attack can be considered justified as a desperate, strategic measure to avoid economic collapse and secure oil supplies.
Quick tip for your worksheet
- Choose which claim you will defend. Then pick 3–5 bullets of evidence from your article/images that best support that claim (dates, embargo details, photos of damaged ships, quotes from leaders, casualty numbers). Use the reasoning paragraph to connect the evidence to your definition of “justify.”
