Why does a two-party political system exist in the U.S.?
The short answer to this is because of the U.S.'s unique winner-take-all politics. This is a result of the U.S.'s plurality voting electoral system. In a plurality voting system the candidate or party that wins an election take all of the positions. This is opposed to a proportional voting system; if an opposing party loses they still get some representation proportional to the amount of votes they receive. Plurality electoral systems often only allow for two (possibly three) political parties to survive since one party is often in-power and the other is not--there is no room for any other parties to exist. However, in many European countries, many--sometimes dozens--of political parties exist because they all get some representation based upon the proportion of votes they receive.

Why don't somewhat rich countries with bountiful natural resources often succumb to dictatorships?
Often called the resource trap, countries that have abundant natural resources but weak democratic institutions often fall prey to dictators. This is because dictators are able to seize there power (i.e. wealth) from the natural resources. They do not have to "bargain" with there citizens via taxes to receive there political power--they can merely seize oil fields and use the proceeds to fund there military and other supporters.

Why did the U.S. enter WWI?
Upon first glance it may seem that the U.S. entered WWI (commonly referred to as the Great War by most historians) due to the sinking of the Lusitania and unrestricted German U-boat warfare. And, although this did play an important part in galvanizing the U.S. public against the Germans/Austrians, the U.S. had already sided with the allies economically. The U.S. had invested in the allies side almost from the beginning of the conflict via loans and trade.
