This paper examines three interconnected national security challenges facing the United States in a globalized context. First, it argues that energy insecurity poses a greater threat than sovereign debt, using historical examples such as World War II and the ongoing China-Japan territorial dispute over the Diaoyu Islands to illustrate how competition for resources drives conflict. Second, it analyzes the security implications of climate change—specifically rising sea levels and drought—for developing nations, drawing on the Sudan civil war as a case study. Finally, it identifies illegal immigration, drug trafficking, and corruption as the three most critical U.S. national security interests in Mexico, concluding that drug smuggling and corruption together represent the gravest obstacles to stability along the U.S.-Mexico border.
Globalization is the integration of trade, economic, financial, and communication resources. Its primary focus is on the free transfer of goods and services across national borders. However, some restrictions are applied under this philosophy — most notably, the movement of people across national borders with little to no interference. This is designed to protect smaller economies and encourage development within these regions. (Dodds, 2012)
The biggest challenge for U.S. national security interests is energy insecurity. All nations require resources such as oil and natural gas to maintain consistent levels of economic growth. Tighter supplies increase the likelihood of conflicts arising over control of those resources. (Dodds, 2012)
A clear example is the territorial dispute between China and Japan over the Diaoyu Islands, driven by the discovery of large oil and natural gas reserves throughout the South China Sea. In order to access these resources, China has questioned Japan's claim to the islands and engaged in aggressive actions to assert control over them, causing tensions between the two countries to rise. (Dodds, 2012; "China Japan Island Dispute," 2013)
This situation challenges U.S. national security interests by escalating regional anxieties and generating greater instability. In the future, any miscalculation could lead directly to open hostilities. Should that occur, the United States would be drawn into the conflict through its mutual defense treaty with Japan. This example illustrates how China's energy insecurity and desire to control additional reserves is creating broader challenges. For the United States, such events risk destabilizing entire regions as competing interests vie to control and exploit resources within their own economies. (Dodds, 2012; "China Japan Island Dispute," 2013)
Historically, energy insecurity has been directly linked to instability in various regions. One prominent example is Hitler's invasion of the Soviet Union, motivated in large part by the desire to control vast natural resources — most notably coal, oil, and iron ore — intended to fuel the Nazi war machine. (Burgan, 2007)
Similarly, a primary reason Japan attacked the American fleet at Pearl Harbor was the U.S. decision to cut off oil supplies needed for Japan's war effort. Japanese military leaders believed that a single decisive blow against the Pacific Fleet would force America to negotiate a peaceful settlement and resume supplying the energy Japan required. The strategy nearly succeeded; only a last-minute decision to send the nation's three aircraft carriers out for maintenance on the day of the attack prevented its full effect. (Burgan, 2007)
These events demonstrate how energy insecurity can motivate aggressive actions by nations. Such competition has repeatedly resulted in increased hostilities and regional instability, making it one of the greatest challenges to the balance of power and a key determinant of the scope and severity of conflicts around the globe. (Burgan, 2007)
Climate change refers to shifts in the Earth's weather patterns resulting from rising atmospheric temperatures. These changes are producing warmer conditions and transforming precipitation cycles. Among the most serious consequences is the accelerated melting of polar ice caps and glaciers, which alters ocean temperatures and causes higher sea levels. As a result, weather becomes more extreme and unpredictable across different regions of the world. (Douglas, 2000)
Rising sea levels affect ocean currents and weather patterns globally. Some regions will experience more precipitation than usual, while others will endure prolonged droughts. At the same time, many population centers are located along coastlines. As sea levels rise, numerous coastal areas will flood, forcing large numbers of people to relocate further inland. For developing countries, this creates security dilemmas by intensifying competition for land between established communities and new arrivals, increasing the potential for internal conflict.
