This volume is a companion piece to What If? and More What If?.

This book concentrates mainly on the history of the US. So we have:-
The Mayflower landing in Virginia instead of Massachusetts and so less religious influence on the US.
Pitt the Elder avoiding the American Revolution.
George Washington being trapped by British troops in Brooklyn before the War of Independence gets fully into stride.
No incorporation of Texas into the Union - and no Vice Presidents automatically succeeding on a President’s death.
No loss of Lee’s cigar-wrapped orders before Antietam and hence a Union defeat in the Civil War.
No (possibly unjust) blaming of a certain Civil War Union general for a near catastrophe. (That circumstance eventually gave us Ben-Hur and all the cultural efflorescences that followed from it.)
A second secession (of Mid-West States) during the Civil War.
Andrew Johnson being assassinated along with Lincoln.
A class war in the 1870s.
A US-Britain war in 1896 (over a border dispute in South America!)
FDR delaying the Pacific War.
Eisenhower taking Berlin before Zhukov and Konev get there.
Joe McCarthy as a Soviet agent. (Not too big a leap for the imagination if you apply the old saying “cui bono” to that Senator’s activities.)
A thawing of the Cold War because Gary Powers’s U-2 mission is cancelled.
The Cuban missile crisis is not resolved safely.
An unassassinated JFK reconciling with Cuba (and resisting embroilment in Vietnam.)
Watergate as only a minor scandal.

All fascinating stuff – if perhaps sometimes the historians assume nothing too much would change thereby.
