A just war can only be waged as a last resort. All non violent options must be exhausted before the use of force can be justified.
We have not used all possible remedies to end the war on terrorism. For instance, we have not yet found Bin Laden and tried him for his actions. This would be a safer and more peaceful way to go about ending this war. Also we should give diplomacy more time. I feel that there are many other ways to fight terrorism without resulting in war. (see attached articles).
The ultimate goal of a war is to re-establish peace. More specifically, the peace established after the war must be preferable to the peace that would have prevailed if the war had not been fought. .
If we went to war with Iraq, then peace would not be re-established. They are still recovering from the pre-gulf war, and there is not much peace there to begin with. If the United States chooses to go to war, peace is the last thing we want them to have. If we wanted to re-establish peace, we would be going about handling the attacks in a different manner, such as the examples above.
The weapons used in war must discriminate between combatants and non-combatants. Civilians are never permissible targets of war, and every effort must be taken to avoid killing civilians. The deaths of civilians are justified only if they are unavoidable victims of a deliberate attack on a military target.
The United States is thinking and discussing the use of nuclear weapons in the fight against terrorism. A nuclear bomb will not only kill the terrorists, but many civilians who had nothing to do with the fight in the first place. Killing civilians goes against the principles of a just war. Therefore, we should not attack Iraq with a nuclear weapon, and they should not threaten the United States with one either.
