The objective of the League of Nations was to keep peace and many countries joined after WWI, but its main flaw was the lack of authority to enforce the decisions reached. It is significant to mention that for example the US was not part of the League of Nations.
<u>When the UN was built after WWII</u>, the Security Council was in fact the organ specifically created in order to address the flaws of the former League, and to be in charge of keeping international peace and security. Anyway, its activity was mostly paralized during the Cold War. After the dismantling of the URSS it has been operating and sending peacekeeping military missions all over the world.
The main functions of the Security Council are the following: the establishment of peacekeeping operation and of international sanctions, and the authorization of military interventions.
The American Revolution began in Massachusetts at Lexington and Concord on 19 Apr 1775. On 3 Sep 1783, 8 years later it officially ended. Although the war took 8 years to end, the fighting was not one constant continuous effort without any major battle being fought after 1781 (Revolutionary War, 1996). The war was victorious with 13 British colonies in North America winning their freedom and becoming what is now known as the United States.
