History often feels inevitable, as though the world always turn out the way it should. But beneath the surface of every textbook chapter lie fragile turning points where the future hangs on by a thread.
Split-second decisions, narrow escapes, and unlikely triumphs shaped the world we now take for granted. Each moment might have unfolded differently, altering the course of nations, ideas, and daily life as we know it.
By stepping back and asking “What if?” we begin to see history not as a fixed path, but as a series of crossroads filled with chance, risk, and human choice. Exploring these near-misses and turning points reveals how easily our reality might have been unrecognizable.
