Problem: Treaty:

Prior to 1871, the government of the United States regularly entered into treaties with Native Americans but the Indian Appropriations Act of March 3, 1871 (ch. 120, 16 Stat. 563) had a rider (25 U.S.C. 71) attached that effectively ended the President's treaty making by providing that no Indian nation or tribe shall be acknowledged as an independent nation, tribe, or power with whom the United States may contract by treaty. The federal government continued to provide similar contractual relations with the Indian tribes after 1871 by agreements, statutes, and executive orders.

Problem: Mali:

In January 2012, an armed conflict broke out in northern Mali, which Tuareg rebels took control of by April and declared the secession of a new state, Azawad. The conflict was complicated by a military coup that took place in March and later fighting between Tuareg and Islamist rebels. In response to Islamist territorial gains, the French military launched Operation Serval in January 2013. A month later, Malian and French forces recaptured most of the north. Presidential elections were held on 28 July 2013, with a second round run-off held on 11 August, and legislative elections were held on 24 November and 15 December 2013.

Problem: Political party:

While there is some international commonality in the way political parties are recognized, and in how they operate, there are often many differences, and some are significant. Many political parties have an ideological core, but some do not, and many represent very different ideologies than they did when first founded. In democracies, political parties are elected by the electorate to run a government. Many countries have numerous powerful political parties, such as Germany and India and some nations have one-party systems, such as China. The United States is a two-party system, with its two most powerful parties being the Democratic Party and the Republican Party.

What are some countries that have multiple powerful political parties?

Germany and India
