I'd go back in time to the mid to late 1800s and buy serious stock in early Rockefeller. Then, I'd fast forward to when it was at its highest and cash out. After that, I'd buy influence and power, changing nothing until the peace conference at the end of WW1, where I'd pay the leaders to vote in favor of keeping their promises to ME tribal leaders and not pin the cost of reparations on Germany, instead setting it up as a group funded project that strengthens the League of Nations. Lastly, I'd ally with and support Red efforts in the burgeoning USSR.
You'd have no little to no anti-western Middle Eastern conflict, the conditions that led to Nazi Germany wouldn't exist, and you'd have a friendly USSR that would be backed by its western allies.
