With the development of the UN, decision making has turned into a global issue rather than an issue that can be contained within a country. What one country decides to do effects almost every other country in the world therefore how one country makes decisions should be analyzed and criticized by others. One of the biggest issues at the moment that affects the entire world is global warming. With issues as big as global warming some countries have begun by taking a stand in trying to resolve or remedy this issue as soon as possible as we can see through the Paris Agreement where various countries have agreed to reduce their carbon footprint by 2020 yet one of the biggest contributors to this global epidemic failed to sign this agreement, the United States. Does it matter that President Trump refused to sign this? Potentially. The power the United States has to drive others to comply and agree with their decisions is greater than we think. Plus, the greater the number of countries that agree to reduce their carbon footprint and ensuring that the other countries within the agreement do the same, the more likely we are to decrease the effects of global warming so that Earth will not be as harmed. Although Donald Trump has made it clear that he wants the US to follow a pattern of isolationism, in today’s world where countries rely on each other for resources and goods, isolationism will not be effective and may trigger consequences that we may not be able to remedy.
