The U.S. won World War I and set up the League of Nations to decide on what to do with Germany and Italy. The Treaty of Versailles was also signed that set limits on the future of Germany. America did not sign due to unrest at home. Actually- The League of Nations was a condition contained within the treaty of Versailles. Because of a lack of support in Congress, the United States never signed this document and therefore never entered this collaboration between nations. Due to the United States' lack of participation, the League of Nations was not long lived, and not until the creation of the United Nation (WWII) did the United States become involved in an international coalition such as this.
I believe the order is:
1.) The US forms SEATO
2.) Diem and JFK are assassinated
3.) 2 US Navy ships are attacked by Vietnamese torpedo boats
4.) Congress passes the Gulf of Tonkin Resolution
5.) Elections that could have reunified Vietnam are rejected
However, make sure to double check these, as I am not 100% sure about the last one. Albeit, I am almost positive that the other four are correct (in relation to the others, that is). Don't take my answer for fact, this is just a shove in the direction (or so I hope).
The mentioned war had a significant impact because the two warring nations developed a sense of nation given that the British lords were fighting the French lords. Following the war, both nations felt a greater sense of unity due to the battles that were fought during the war.
Advantages
They need not fear that their vote will impeach them. In other words they get to vote their conscience.
The experience they gain from the years of service makes them experts in the particular law they are judging.
Disadvantage
Should they become ill (I'm thinking of the Supreme Court here), their vote may mean something if they are not there.
They become to set in their ways.
