If isolationism is out of date, what is the foreign policy of the United States? In the years following World War II, the United States was generally guided by containment, the policy of preventing communism from spreading beyond the countries that were already under its influence. The policy applied to a world divided by the Cold War, a struggle between the United States and the Soviet Union. But is America`s sublime position sustainable? On the military front, the gap between the United States and all the others is widening. While defense spending is declining in most other countries, U.S. defense spending is growing rapidly. The increase in defence spending claimed this year is greater than the overall Chinese defence budget. What is most remarkable is that America can afford to spend more. Defence spending accounts for a smaller share of U.S. GDP than it did a decade ago – and even increases planned by the Bush administration will give a total budget of about 3.5% of GDP, or about half of cold war highs.
It is unlikely that any country or group of countries will devote the necessary resources to military competition with the United States, let alone to surpass them. Carefully planned terrorist acts in the United States, Asia and Europe have brought a new kind of enemy into the balance of power – non-governmental or non-governmental organizations such as Al Qaeda and IS (or ISIL), which are made up of different terrorist cells in many countries and on every continent. In an economic boycott, the United States ends trade with another country unless it changes a policy contrary to the United States. Stopping trade means that U.S. products cannot be sold in that country and their products cannot be sold in the United States. For example, in recent years, the United States and other countries have implemented an economic boycott of Iran as it degenerates the development of its nuclear program. The recent Iran nuclear deal is a pact in which Iran says it is ready to end nuclear development, while the United States and six other countries lift economic sanctions to restore trade with Iran. Barriers to trade include tariffs or charges for transporting goods from one country to another. Protectionist trade policies increase tariffs, making it difficult for imported goods, which are now more expensive, to compete with domestic products at a price. Free trade agreements aim to reduce these barriers to trade. In U.S. history, critics have argued that presidents have used democracy to justify military intervention abroad.
  Critics also accuse the United States of helping local military personnel overthrow democratically elected governments in Iran, Guatemala and other cases. David McKay, author of the American Politics and Society, is one of the three main distortions of information by the media: „Give a high priority to American news at the expense of foreign news. And when the United States acts militarily abroad, this „foreign news“ supersedes other foreign news. Mr. President sets the tone for the whole of foreign policy. The Department of Foreign Affairs and all members design and implement all the details of the President`s policy. Congress approves the selection of the president for ambassadors and may declare war as an incidental function. The President of the United States negotiates treaties with foreign nations, and then the treaties only enter into force if they are ratified by two-thirds of the Senate. The president is also commander-in-chief of the U.S. armed forces and, as such, has broad authority over the armed forces. The Secretary of State and Ambassadors are appointed by the President with the Council and the approval of the Senate.
