In 1856 Franco-Russian-British peace was signed at the Congress of Paris. Cavour succeeded in having one of the sessions expressly devoted to discussing the "Italian problem": He was able to publicly defend the idea that the repression of the reactionary governments and the The policies of the Austro-Hungarian Empire were the real culprits of the revolutionary anxieties that were forming throughout the peninsula and, above all, that these revolts in Italy could degenerate into a revolutionary threat to all the governments of Europe, thereby increasing the Franco-British concern in the "Italian problem".
Here is how it was explained to me. WW2 was blamed pretty much entirely in Hitler, yes obviously there were so many other factors, and decisions that made the total, destruction of everything, but everyone blames Hitler for the start of it all. In this passage though, it sounds like the blame is on the other political advisers, and his foreign minister. Like they were supposed to have pushed for more meetings, or tried to make Hitler see reason.

The two sides of the debate over slavery were divided between the two main sections of the United States; the North and South. Many Northerners viewed slavery as evil and wrong and some were involved in the abolitionist movement. The North did not obey fugitive slave laws because they said they were cruel and inhumane. No states in the North allowed slavery and the North and the abolitionists who lived there harbored fugitive slaves and helped them escape to Canada along the Underground Railroad. In the South, on the other hand, the people said that slavery was necessary to their way of life even though the majority of southerners did not even own slaves. Those who did own slaves, said slavery was good for the slaves because they were cared for in every way and given a job and that slavery was good for the slave owners because it allowed southern whites to achieve a high level of culture.
