How would the Second World War change if the United States adopted Pacific first instead of Europe first?
Short answerEuropean amphibious campaigns would be delayed, but North Africa might change less than expected and Japan could face invasion before atomic weapons were ready.
NotesBritain would endure more pressure and the invasions of Sicily and Italy would move later, but North Africa might still finish on a similar timetable even without Operation Torch. The largest uncertainty is whether earlier concentration against Japan produces an invasion before atomic weapons are available.
