An issue with this point however, is that, while the army believed that the Americans could be scared into suing for peace, the man responsible for the navy, Yamamoto, was not convinced. The difference here, was that Yamamoto had been to the United States and saw what the American people were doing during the Great Depression. He was convinced that the Americans were sturdier people than their propagandists propagated. The Army officers though, they bought the propaganda hook, line, and sinker. They overruled the one man who had been there, and ordered him to draw up the attack plans. Pearl Harbor really wasn't about trying to force the American Surrender, it was about getting the Carriers. Yamamoto realized that the only way they were going to have a chance in this war was to sink the three US Carriers, and then to follow it up with quick decisive strikes that put the US on its heels. Had the Carriers been there, and sunk, I think a follow up operation to take Hawaii would have been worked out. But when they missed the Carriers, Yamamoto knew the war was lost, because they could not hope to keep up with American Industry, and those three Carriers were all the Americans needed to hold their operations at bay long enough for the US to build who knows how many more (we do know, now, but back then they didn't). Which is why Yamamoto tried desperately to engage and sink those Carriers in early 42.
