/My thought based on my limited resources, and I have no intention to insult or provoke anyone.
Crisis of Confidence
Bush government told lies at the start of Iraq war. Some people defended it that Parliament knew it too at that time. IMO, which can't remove the
suspicion that if government told you a lie in this issue, then they could tell you lies in any other issue. Which is the key problem, crisis of
confidence. It depends on constitution, laws and regulations to manage a country, instead of government self-conditionality. They can produce
mendacious reason to deal with foreigner, why couldn't they do it to domestic citizens to realize their aim? Nothing can safeguard it. People will
deepen the sense of mistrust, which is the start of many bad things.
Resources
I absolutely support Iraq action, because Iraq is a dictatorship. The result is good, because I know the feeling of people living in dictatorial
circumstances. But I believe that there are economic reasons too, Or better, if there is oil in the target conutry, why don't you draw advantage from
it when you carry out military action? I think it's normal. So why you can't withdraw from Iraq qucikly, because there's not merely military
consideration.
betray
World issues are always conducted by multiple powers, so it can't be simply concluded to "one" or "another".
America ever supported Saddam Regime in their establishment and Iran-Iraq War, and more, Bin Laden gained his military power through the support of
America too.
Chinese Link America government must be more hurted and provoked by the attack of
military power created by their backing and they felt being betraied, so they sticked to eliminate them in spite of other countries opposition.
Blood
I know some massacres and mistreatness happened in Iraq, but I don't think they are important evidences to judge whether the war is justice or not.
War is war. You can't control everyone's action. It ain't all the people in domestic are good and honest, so is in military. Moreover, it's normal
for soldiers doing something unwisely when they were provoked by their companion raided and killed.
Insurgents
It's also normal that there are some insurgents, who are different from terrorists, fighting against coalition for their lands being occupied,
because some outrages are really true and every nations have nature sense of exclusion for outcomer. Moreover, Saddam regime was setted up by the
support of America too. How can they not suspect the real aims of America?
