Since 1945, the United States has been involved in numerous global conflicts - the US needs constant warfare as a part of its economy, which is linked to the Military Industrial Complex.
America's rise to global power from 1776 was driven by territorial expansion, economic growth, military involvement in world conflicts, and strategic power diplomacy.
