Failed European revolutions encouraged Union underestimation

The thread asks whether recent European experience encouraged Union leaders to underestimate secession. Liberal and nationalist uprisings connected with Italian unification had often been put down by standing armies, making a regional rebellion seem manageable by analogy. A reply stresses that the Confederacy represented a much larger rupture than those revolts and invokes the American Revolutionary experience as a warning. An important demographic qualification is that the seceded territory was extensive, while the Union's population remained much larger. The exchange shows how a familiar analogy can mislead unless scale, population, and political context are compared as well.
