The U.S. economy accomplished astonishing feats during World War II. Manufacturers have re-equipped their factories to produce war goods. But it wasn`t enough. Soon, huge new factories built with public and private funds emerged throughout the country. Millions of new jobs have been created and millions of Americans have moved to new communities to fill them. Annual economic output, as measured by gross national product (GNP), more than doubled from $99.7 billion in 1940 to nearly $212 billion in 1945. The Stockholm International Peace Research Institute (SIPRI) has estimated military spending at $1822 billion as of 2018.  This represented a relative decrease compared to 1990, when military spending accounted for 4% of world GDP. Part of the money is spent on the acquisition of military equipment and services from the military industry. According to SIPRI, the combined arms sales of the 100 largest arms production and military services companies (excluding China) totaled $420 billion in 2018.
 This was 4.6 percent more than revenue in 2017 and marks the fourth consecutive year with growth in the top 100 arms sales. In 2004, more than $30 billion was spent on the international arms trade (a figure excluding domestic arms sales).  According to the Institute, the volume of international transfers of large arms in 2014-18 increased by 7.8% compared to 2009-13 and 23% higher than in 2004-2008. U.S. forces were largely composed of “citizen soldiers,” men and women of civilian life. They came from any state of the nation and from all economic and social strata. Many were volunteers, but the majority, about 10 million, entered the army through compulsory military service. Most of the conscripts were assigned to the army. The other services initially attracted enough volunteers, but eventually their ranks also included conscripts. The cybersecurity sector is becoming the leading defence industry, with cyber attacks being considered one of the main defence risks over the next decade, as cited in NATO`s 2013 report.  Significant investments have therefore been made in the cybersecurity sector to produce new software to protect the ever-increasing transition to digital hardware.
For the military industry, it is essential that protective devices be used for systems used for information, surveillance and information gathering. In addition to transforming industry into war production, American industry also provided much of the military equipment needed by the Allies, including the United Kingdom and the Soviet Union. Arms control refers to international restrictions on the development, production, stockpiling, proliferation and use of small arms and light weapons, conventional weapons and weapons of mass destruction.  It is usually exercised through the use of diplomacy that attempts to convince governments to accept such restrictions through agreements and treaties, although it may be imposed on non-consenting governments. . . .
