Again, you're writing nonsense, both from a historical and logical point of view.
The Japanese military establishment in the 1930's was hellbent on expanding their influence. They had defeated Imperial Russia, and felt like it was their time in the sun. They had complete dominance over the government, and chose, yes chose to undertake a path of aggression towards their neighbors. First they started with Manchuria, and installed a puppet government. Then they moved on China.
Unsurprisingly, this provoked concern amongst other countries that had interests in the region. The Dutch (Indonesia), the British (Singapore and Malaysia), and the US (Philippines) realized the threat posed by the expanding Japanese empire. At the time the US was still in the midst of the Great Depression and was in no state to challenge Japan militarily, so they used an oil embargo to try and persuade the Japanese to adhere to international agreements.
It wasn't until 1941 that the US cut off oil to Japan. At this point, Japan had already invaded and controlled Manchuria, invaded and controlled a majority of China. When Japan seized control of Indochina, the US and allies attempted to influence Japan to leave Indochina by seizing US held assets, and embargoing oil. Japan had anticipated this and began a regional war attacking both the US, Dutch and UK territories.
You seem to imply that these things just "happen" and that no one is in control or making decisions. While history often seems to have an impetus of its own, it's the result of choices leaders and people make. Tojo and his warmongers sought out conflict in the region, dismissed counsel from wiser heads, and set Japan on a course to ruin.
Hirohito made a choice to continue to allow the militarist factions in the Japanese government to hold sway. But to point to the day the go ahead was given to Isoroku Yamamoto as the crux of the issue is to miss the point; he holds responsibility, as did the other military leaders and the Emperor. They knew the risks when they invaded Indochina; they knew the latent power of the US, but they underestimated their foes, and overestimated their own ability to wage war.
Attacking Pearl Harbor was irrational, both in hindsight, but also in terms of what the Japanese knew at the time. It was less than a year before the IJN began to experience catastrophic losses, and after Guadalcanal, there IJN was on its back foot for the rest of the war.
What could Japan have done differently? They could have restrained themselves from invading Indochina and prompting the expect oil embargo. If that wasn't feasible, they could have relinquished control of Indochina, though that would have caused a tremendous loss of face. They could have attacked and invaded the Dutch East Indies to gain oil, and odds are the US wouldn't have gotten involved. Great Britain was pretty busy with fighting Germany at the time and wouldn't have been able to help the Dutch much. If they did, the Japanese would easily defeat them in Singapore, as they did on Dec 8th.
The isolationist sentiment in the US at the time wouldn't have allowed the US to intervene. We weren't intervening in the European war, despite Lend-Lease, and sure wouldn't have intervened in Asia unless directly attacked.
