In his Iron Curtain speech, Winston Churchill affirmed his wish to side with the United States against the Soviet Union  and his belief that only the United States possessed nuclear weapons.

Winston Churchill used the Iron Curtain expression to refer to the border, not only physical but also ideological, that divided Europe into two blocks after World War II. Churchill popularized the term at a conference in the United States in 1946, when he said:

"From Stettin, in the Baltic, to Trieste, in the Adriatic, an Iron Curtain has fallen on the continent".

The frontier of which Churchill spoke divided the socialist states, headed politically, economically and militarily by the Soviet Union, and the capitalist states, aligned with the United States.

here are some events that to cause increased conflict between the north and south

1) mexican cession- gaining modern day california, utah, arizona, and new mexico from mexico. caused southern and northern politicians to fight over whether or not there would be slavery in these newly acquired territories.

2) uncle tom's cabin- this famous book described the cruelty of slavery in the south during the antebellum period, causing more northerners to support abolition and southerners to resent the book as they felt it unfairly depicted southern society.

3) kansas- nebraska act- disagreements over whether or not kansas and nebraska would be free or slave states caused issues between northern and southern politicians in congress.

4) bleeding kansas- this fighting took place in kansas after congress allowed this territory to vote on whether or not they would have slavery. citizens were killed and buildings were destroyed during this fighting.
