Why do you think that yamamoto opposed the attack

Admiral Yamamoto was a patriot, that cannot be doubted. Here is how he tried to stop World War II but ended up fighting in it anyway.

Explanation:

Brave, urbane, and complex, Admiral Isoroku Yamamoto was Japan’s greatest naval strategist and the architect of one of the most stunning achievements in the history of modern warfare.

Fluent in English, he studied in the United States and claimed many American friends before he became one of their deadly enemies. A solid and widely respected man, he argued passionately for peace in the 1930s while fascism spread in Europe and a fanatical militarist faction in Tokyo was calling for aggressive expansion in the Far East. Yet Yamamoto was a patriot to the bone, and when ordered to fight, he waged war with a vengeance.
