Question

1. why did the u.s. fight the battle of iwo jima?

so it could invade japan itself
so it could recapture the philippines
so it could protect australia from invasion
so it could protect hawaii from invasion

Explanation:

Analyze the strategic context of Iwo Jima

The Battle of Iwo Jima (February–March 1945) was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army.

Evaluate the strategic purpose of the battle

The island was strategically located halfway between the Mariana Islands (where U.S. B-29 bombers were based) and the Japanese mainland. Capturing Iwo Jima provided airfields for emergency landings of damaged bombers and allowed fighter escorts to accompany bombers directly to Japan, serving as a crucial stepping stone toward the ultimate goal of invading the Japanese mainland.

Assess the incorrect options

• Recapturing the Philippines: This was already largely underway or accomplished by late 1944 under General MacArthur, far to the southwest of Iwo Jima.
• Protecting Australia or Hawaii: By 1945, the threat of a Japanese invasion of Australia or Hawaii had long passed, as the Japanese military was entirely on the defensive and retreating toward their home islands.

Connect to the correct option

Therefore, the primary strategic reason for fighting the Battle of Iwo Jima was to secure a base close enough to support the air campaign and prepare for the eventual invasion of Japan itself.

Answer:

• so it could invade Japan itself (Correct answer)
• so it could recapture the Philippines
• so it could protect Australia from invasion
• so it could protect Hawaii from invasion
