Iraqi Federalism and Iran's National Security; Opportunities and Challenges

The US led coalition forces attack to Iraq on the pretext of WMD has turned this country''s events into one of the main topics discussed by the experts in political and international issues. Based on the new Iraqi constitution، which was approved by Parliament and the majority of Iraqi people، the government was established as ''democratic، federal parliamentary republic''. This paper tries to answer the following question: what is the impact of the federal system in Iraq on Iran''s national security? To answer this question، authors have used descriptive-analytical method. Compared to Iraq’s thereat، as a unitary state، for Iran’s national security (as was the case of the last Iran- Iraq war) or as a distorted country which paves the way for inference of trans regional powers in opposition to Iran’s national interests، it seems that the new Iraq federal system regardless of some challenges that may cause for neighbors including Iran، can be the best model for national security.
