According to the Just War Theory, violent conflict should be undertaken under specific philosophical, political, and religious criteria. The invasion of Iraq is one of the common acts of war that the American nation has been involved in. The war on Iraq was justified under the just war doctrine. According to the doctrine, the damage caused by an aggressor to the community or nation should be certain, lasting, and grave. When terrorists conducted their attacks on the nation of America on 11th of September in 2001, the results were not only certain and grave, but have lasted over the course of time. People not only lost property during the September 11th attacks, but also lost lives, friends, and loved ones (1 Peter 2:13-17, King James Version).
The just war doctrine also stipulates that all other means and channels instituted to putting an end to the issue must have been explored and proven to be ineffective or impractical. After the September 11th attacks, the United States government explored every option there was to end the war by terrorists but the more the United States tried to solve the issue on grounds on diplomacy, the more the terrorists stood their ground (1 Timothy 2:1-2, King James Version).
According to the just war doctrine, a serious success prospectus has to be presented in the initiative to go to war. In the war against Iraq, the United States was certain that taking out the current forms of government in the targeted nations would not only put an end to terrorism, but also help the communities to rebuild their countries along productive lines (1 Peter 2:13-17, King James Version).
According to the doctrine of just war, the use of force, arms, or any other means to stop a war must not yield disorders and evils that seem to be greater than the ill that ought to be eliminated. According to American intelligence agencies, the terrorist attacks had been undertaken my militant groups which were structured into cells. All the people involved in the attacks were ready to die in their undertakings and thus America was only concerned with people who were out to cause harm to innocent American citizens (1 Timothy 2:1-2, King James Version).
