The Impact of US Foreign Policy (Trumpism) on Israel on the National Security of the Islamic Republic of Iran

President Donald Trump's policies around the world, with their unique personality traits (pragmatism), evoke new passive approaches to US foreign policy. Trump has taken significant action against Iran since the early days of his stay in the White House through Israeli lobbies. At the annual meeting of conservative social activists in Washington, he cited support for Israel as the main reason for leaving the UN Security Council. Undoubtedly, the issue of Iran's position on Israel, as well as the policies of the United States and its current president towards the regime, has caused acute problems in Iran's foreign relations. Therefore, the purpose of this study is to examine the foreign policies of the US government towards Israel and its impact on the national security of the Islamic Republic of Iran. In this regard, the main question of the research is based on the impact of US foreign policy during Donald Trump's presidency on Israel on Iran's national security. The present study uses analytical-descriptive method and in the context of realism. Aggressive assumes that Trump's policies toward Israel, such as recognizing Israel's sovereignty over the Golan Heights, supporting the development of Israeli settlements, moving the US embassy to Jerusalem, etc., are ineffective. It will not be the key to national security in the Islamic Republic of Iran.
