Foreign Policy for the Iranian government is influenced by a number of contentious issues; regional competition, proxy conflicts, nuclear enrichment, the petrochemical industry, a deep religious divide, and changing international power dynamics. Regional conflict and competition for influence across the Middle East is set against Israel and Saudi Arabia, but has a backdrop of other major global powers such as United States of America, Europe interference and security requirements of other major global powers. The changing dynamics of the global economy and sentiment in the U.S. administration (for example), has contributed to the exclusion of Iran from the international economy through the use of economic sanctions. The withdrawal from the Joint Comprehensive Plan of Action (JCPOA), falls in line with current trends towards protectionist and less globally focused state behavior in the U.S. administration of President Donald Trump. Military strikes against Iranian targets within Iraq and Syria in late 2019 and early 2020 have intensified hostility in the region.
