Compare and contrast the green party’s stance to the libertarian party’s stance on social issues

Answers

The Libertarian Party (LP) is a political party in the United States that promotes civil liberties, non-interventionism, laissez-faire capitalism, and limiting the size and scope of government. The party was conceived in August 1971 at meetings in the home of David F. Nolan in Westminster, Colorado, and was officially formed on December 11, 1971 in Colorado Springs, Colorado. The founding of the party was prompted in part due to concerns about the Nixon administration, the Vietnam War, conscription, and the introduction of fiat money.

The party generally promotes a classical liberal platform, in contrast to the Democratic Party's modern liberalism and progressivism and the Republican Party's conservatism. Gary Johnson, the party's presidential nominee in 2012 and 2016, claims that the Libertarian Party is more culturally liberal than Democrats, and more fiscally conservative than Republicans. Current fiscal policy positions include lowering taxes, abolishing the Internal Revenue Service (IRS), decreasing the national debt, allowing people to opt out of Social Security and eliminating the welfare state, in part by utilizing private charities. Current cultural policy positions include ending the prohibition of illegal drugs, advocating criminal justice reform, supporting same-sex marriage, ending capital punishment and supporting gun ownership rights.

It is currently the third-largest political party in the United States by voter registration. In the 2020 United States elections, the Libertarians gained a seat in the Wyoming House of Representatives, giving them their first state legislative win since 2000. As of 2020, there were 211 Libertarians holding elected office: 89 of them partisan offices and 122 of them non-partisan offices. 58 of the partisan offices are minor positions in Pennsylvania. There are 609,234 voters registered as Libertarian in the 31 states that report Libertarian registration statistics and Washington, D.C. The first electoral vote for a woman was that for Tonie Nathan of the party for vice president in the 1972 United States presidential election due to a faithless elector supporter who eschewed his expected vote for Richard Nixon.

Following the victory over Great Britain in the War of 1812, the United States experienced a period of _______________ where people felt great pride and loyalty to their country as a whole. *

Answers

Answer:

Nationalism.

Explanation:

John Monroe was an American diplomat, lawyer and statesman who was elected as the fifth president of the United States of America, he served from 1817 to 1825. President Monroe was born on the 28th of April, 1758 in Monroe Hall, Virginia, United States of America.

After the War of 1812, the United States of America and Great Britain had series of improved relationships with one another. These mutual relationships gave rise to the signing of the 1817 Rush-Bagot Pact and Convention of 1818 which played a significant role in the resolution of longstanding boundary disputes with respect to the 1783 Treaty of Paris.

Under President James Monroe, the 49th parallel was set as the boundary between the United States and Canada by Convention of 1818, which was signed on the 20th of October, 1818 in London, United Kingdom.

Following the victory over Great Britain in the War of 1812, the United States experienced a period of nationalism where people felt great pride and loyalty to their country as a whole. This act of nationalism wasn't unconnected with the expansion of the economy of the United States of America and the development of social infrastructures.

What is Multilateral relationships?

Multilateralism is the process of establishing connections between groups of three or more states. Multilateralism is often regarded to involve a variety of qualitative elements or guiding principles that shape the nature of the agreement or organization in addition to that essential quantitative feature.

Examples include the World Trade Organization, NATO, and the United Nations. Upholding international peace and security is the core duty of the United Nations, an intergovernmental organization. As a result, the group acts as a focal point for coordinating the policies of numerous nations.

Since lateral refers to "side," multilateral effectively means "many-sided." As a result of their belief that the best answers are found when the most number of countries in the world participate in negotiations, multilateralists frequently support strengthening the United States.

Thus, option A is correct.
