The role of the commander in chief remains relatively unchanged. The president of the United States remains the ultimate leader in military affairs. Under his command, the Military can carry out invasions as seen in recent years in the middle east. Despite the Congress being the only political entity who can officially declare war, the President has authorized most military actions throughout history.Congress has only formally declared war five times. These five declarations came from the War of 112, Mexican-American War, Spanish-American War. And both World Wars. All other military actions ad invasions have been done so by order of the president. Proving that the president is the ultimate figure when it comes to U.S. Military action and this still holds true today. In the aftermath of the atomic bombings of Nagasaki and Hiroshima and Japan’s hesitant surrender caused political and military leader to underestimate the seismic shift of the balance of world powers. As a result of their wartime alliance, the United States would assist Soviet Russia in gaining a significant position as a world power. Due to its newly acquired power, the Soviets would unwillingly surrender land gain made during the war. This would be taken as an act of hostility by the United States This proved to be the catalyst that forced the United States Military response to that of containment. This strategy of containment could be described as a powerful military, economic, and political tactic that would contain and stop the spread of communism throughout the world. These actions were be taken by the United states Leader as is was clear that no nation wanted to take part in another World War. The United States and Russia would never directly fight one another, this strategy of containment would spark various proxy throughout the world. This policy of containment would be the quintessential role of the military until the fall of the Soviet Union in 1991, bringing the United States to become the only remaining world superpower. The cold war also define the United States political role in world affairs as it would accumulate over 50 military alliance and have a multitude of troops stationed throughout the world many in Asia along the Sea of Japan and the Middle East. Despite the end of the Cold War, the United States increased military activity throughout the world. The Persian-Gulf war was the first post-cold war conflict. The With issues in Iraq and Afghanistan rising, the presence of US troops began to increase steadily in the region.These actions in Iraq and Afghanistan were the turning point in United State Military Strategy. The United States would leave it stance on containment and embarks on its new strategy of power projection. During the years following the collapse of the Soviet Union, The United States intervened in the various nations such as Somalia, Bosnia, and Haiti. These military interventions had serious opposition from within and outside the government. This would be the course of action until the attacks on september 11, 2011. The attacks on 9/11 would lead the Bush administration to issue there new foreign policy. The Bush administration would declare the ” War on Terror” which would bring open and covert military operations to protect and defend from the acts of terrorism. This decree would start the first war that would not be fought between nations but against organizations. This stance on foreign policy is main source of strategic development in today’s military.
