Part A
United State was initially very reluctant to join the World War 1 as it was aware of the consequences it would have on the economy and to the many Americans who had emigrated to various parts. However, it reached to some point when it was decided that America had to join. The first reason in this case was because of a decline in business and commercial activities. This is because many countries in Europe were commercial partners and hence their participation in the war resulted into economic downturn of the country (Murphy, 2004).
The other reason for the entry of US into the war was the issue of the submarine. In this case, major oceans and seas were closed such that Americans were not allowed to escape from war and trading across countries was blocked. In the attempted to cut down supply of food and weapons to Germany, the Royal Navy blocked and seized American trade ships. This triggered Americans to enter into the war.
The other aspect which drove America to enter into the war was the loans it had offered to European allies. It was clear to some points that these allies were almost defeated in the war which meant that they could not be able to pay debts to America when dominated by other countries. The joining into the war was an economic interest (Murphy, 2004).
Part C
Presidents Roosevelt and Woodrow are highly remembered for their role they played during the progressive era. They were aware of the challenges which resulted from industrial and commercial activities. However, the two differed in that they had a different perspective about the problems and solutions. For Roosevelt, increasing efficiency through business and private sector and legal framework against the abuse of power would have saved the American people from these problems.
On the other hand, Wilson was highly against monopoly by the government in various sectors and decided to abolish it. To him, monopoly was unproductive and could not be relied on improving situations in the economy. Roosevelt advocated for strict legislation to reduce evil in businesses. However, Wilson was in view that capitalism will also lead to monopolistic business operations and hence monopolies should not be allowed entirely (Morrisey, 2009).
