What if Josef Stalin had been a healthy, big strapping man, instead of five foot three, with a crippled left arm?

One of the aspects of Josef's Stalin's life and career that I think is underemphasized, is that he was a very small man, and, from childhood, somewhat crippled. His left arm had been badly mangled when he was a boy, and he never recovered the full use of it. And, with a drunken father who had deserted the family, how on earth did this young man even manage to survive? These days, many comparisons are being made between Josef Stalin, Adolf Hitler, and Vladimir Putin. Actually, Putin had a relatively easy time of it compared to Stalin -- he was bigger, healthier, and he had both his parents. He was poor, but, his major problem was merely bullying from other children, so he became a tough street fighter. Stalin never had that option, he had only one good arm, and he was too small to really fight, anyway. As for Hitler, he was rather well off until his father died, then lived pretty well off his mother's pension. With his mother's death, his situation worsened, and he had to scrape by a very bare living as a not particularly brilliant painter. Still, what really toughened Hitler up was spending 1914-1918 in the trenches on the Western Front, dodging death as a messenger, and winning the Iron Cross First Class in the process. Stalin never faced this level of constant danger, but, perhaps that's why Stalin didn't have Hitler's sense of invulnerability and manifest destiny. Stalin had a pretty good education as a teenager in a seminary, as a teenager, until he was expelled for communist tendencies and insubordination. After that, how does a tiny, impoverished, crippled man survive in Tsarist Russia? On his wits! Stalin developed a genius for reading people and situations, and manipulating them to his advantage. He survived and triumphed on the streets, in prisons, in armed conflict, and in every other situation. He could be seen as a criminal, a revolutionary, an opportunist, but, never a fool! So, what if Stalin had been a healthy, strapping young man? He wouldn't have been Stalin, he would have never needed to develop the incredible social skills he possessed, and world history would be a lot different.
