Answer:
The reason why Americans in the East and North were less eager for war than Americans in the South and West is because "Americans in the South and West feared an end to slavery", since the election of Lincoln.
Explanation:
The development of the East African coastal region was greatly influenced by it s excellent strategic position. It became a trading center where goods from three continents were passing by, and lots of money, as well as innovations and technologies were coming in this part of the continent.
If the situation was different, like suggests, if the region was an inland desert or mountainous area in Africa, than it was going to be a very backwards region in every aspect. The people would have steel been living in primitive tribal societies, and there's big possibility that they were going to practice a nomadic lifestyle as well. And those kind of conditions will not allow the formation of developed society, or great empire.
Yes, the United States should have joined the League of Nations.
The League of Nations was created after World War I and was made by the countries that had won the war. They wanted to try to keep the peace and hopefully prevent another world war.
The catch is, the League of Nations was essentially useless. It was<em> </em>very weak and obviously did not prevent World War II from happening. The American public was not interested in joining, the League had no real power to enact any rules, they had no troops whatsoever, and the League was not representative enough to do anything.
While the League of Nations was very weak and useless, it was still a good idea. I believe the United States should have joined the League of Nations because of this. Since it was a good idea, the United Nations was made after the League ended. The United Nations is much more powerful and learned from the flaws that the League of Nations endured.
