The region which is now threatened by Soviet troops in Afghanistan is of great strategic importance: It contains more than two-thirds of the world's exportable oil. The Soviet effort to dominate Afghanistan has brought Soviet military forces to within 300 miles of the Indian Ocean and close to the Straits of Hormuz, a waterway through which most of the world's oil must flow. The Soviet Union is now attempting to consolidate a strategic position, therefore, that poses a grave threat to the free movement of Middle East oil.
This situation demands careful thought, steady nerves, and resolute action, not only for this year but for many years to come. It demands collective efforts to meet this new threat to security in the Persian Gulf and in Southwest Asia. It demands the participation of all those who rely on oil from the Middle East and who are concerned with global peace and stability. And it demands consultation and close cooperation with countries in the area which might be threatened.
Meeting this challenge will take national will, diplomatic and political wisdom, economic sacrifice, and, of course, military capability. We must call on the best that is in us to preserve the security of this crucial region.
Let our position be absolutely clear: An attempt by any outside force to gain control of the Persian Gulf region will be regarded as an assault on the vital interests of the United States of America, and such an assault will be repelled by any means necessary, including military force.-- President Jimmy Carter 1980 State of The Union Address
Someone needs to quickly explain to me again about the lesser of two evils or else I might come to hold the heretical belief that both parties's leadership is committed to an imperialist foreign policy for the United States.
The United States of America is prepared to use all elements of our power, including military force, to secure our core interests in the region. We will confront external aggression against our allies and partners, as we did in the Gulf War. We will ensure the free flow of energy from the region to the world.--President Barack Obama 2013 United Nations General Assembly Address.
