I want to know the answer to the following question:
Why did General MacArthur suggest an amphibious landing at Inchon?
All the background I'm provided with is that "On 6 July, he ordered Major General Hobart R. Gay, Commander, 1st Cavalry Division, to plan the division's amphibious landing at Incheon; on 12–14 July, the 1st Cavalry Division embarked from Yokohama, Japan to reinforce the 24th Infantry Division inside the Pusan Perimeter.". Is that enough to answer the question?
Answer: no
