Currently, the United States and its allies are in deep negotiations to persuade Iran to abandon its nuclear enrichment program. Still, the United States is faced with another challenge in its foreign endeavours that of ensuring that a stable unity government is established in Iraq. The objective is to establish a unity government in Iraq that has minimum interference from Iran. The US economy is no longer favourable to support extra expenditures on international operations such as Afghanistan and Iraq wars. Thus, US President Barrack Obama is striving to keep his commitment to withdraw all the US troops from Iraq. However, the main problem is that Iraq is still not politically stable and the dilemma is what would be left behind once the US troops in Iraq are withdrawn from the country (Neary 34). The other dilemma is how Iran would be prevented from interfering in the internal affairs in Iraq since the possibility of terrorist groups taking charge of the country are high when the US troops are withdrawn from Iraq. For the past four years, Iraq under the leadership of Prime Minister Nouri al-Maliki has not yet achieved the desired level of democracy. Going by the WikiLeaks documents released recently on the Iraq war numerous cases of rape; murder and torture by security forces are still prevalent in the country. It is quite evident that following the just-concluded parliamentary elections in Iraq where Iran had a big role in causing a stalemate in the formation of a new government Iraq is far from stable. A fragile deal aimed at forming a unity government is now prevalent in Iraq which means that Ayad Allawi, the main opposition candidate may be forced to take up the position of the national security overseeing committee because he had a majority of the votes in the just-concluded parliamentary elections. With such a position in the hands of an opposition leader and the main rival of the ruling prime minister, it is obvious that Iraq’s national security might be at stake. However, this plan might work for the benefit of the country particularly because Ayad Allawi will be able to prevent the domination of Iran in the internal affairs of Iraq. The greatest mistake the world leaders and the international community can make in helping Iraq achieve the desired level of democracy is to negotiate with Iran on its role in Iraq. The reason is that the United States has begun the war in Iraq and it is the US that should play a major role in ensuring that Iraq gets back to its feet and the desired levels of democracies are achieved. Negotiating with Iran’s leftist agents which have continued to meddle in Iraq’s internal affairs to advance the interests of Iran would be detrimental because Iran would not agree to leave Iraq. The purpose of this paper is to explore the possibility of achieving lasting peace in Iraq. The main argument is that there is a possibility for a just and lasting peace in Iraq. “Just peace” is a term that can be defined depending on how the war was fought in Iraq, how the war was conducted and the understanding of the just war. For example, the term “just peace” is derived from the tenet of a “just war”. A just war refers to the rules of war which includes le
