What, the two-term abyss known as the Presidency of Texas? Cactus Jack did well by the rural part of the country, hence the existance of the TVA, Greater Utilities of Texas/GUTS, Central Cascadia Industrialization Company/C3I, and the Dakotas-Iowa-Minnesota-Wisconsin Trust/DIMWIT corporations. His failure to back deficit spending slowed any hope of economic recovery and caused first Wilkie to be in the White House then Dewey. Wilkie was dragged into the European war after German submarines torpedoed US ships carrying relief supplies to the UK, but by that point in early 1943 the world was *hurting*. Had Cactus Jack or Wilkie helped the Russians more maybe the war would have ended in 1946 or even 1945, instead the 'Paris Bluff' ended the war just as the Western Allies approached Metz and Germany claimed it would launch a nuke at the Eiffel Tower if the ground offensive were not ended. Japan succumbed to the US drops almost a year earlier in mid-1947 and Soviet remnants carved out the Trans-Siberian collective at the Ub, but a strangely 'reformed' uber-Germany would never exist nor would we likely see man walking on Titan or living on Mars within half a century. Certainly more than twenty nation bloc-alliances would remain, maybe ten times that number, had decolonization and the need for coalitions to match the might of Europe not come to pass.
In other words the specifics would be impossible to predict, as would the number of people likely surviving the atrocities of the 'Purity Program' recently released from their archives, but such a world would probably be unrecognizable.
