Here are the opinions from those that really count.
Taken from BBC.com
From BBCArabic.com: I am surprised at those who describe terror as resistance. Where was this resistance during Saddam's reign? Wasn't there any injustice then? Did he not kill thousands in cold blood?
Tariq, Baghdad
From BBCArabic.com: Some are shedding tears for Falluja and for the terrorists and murderers, but no-one seems to have spared a thought for the bereaved families who have lost loved ones because of the car bombs etc, manufactured by those criminals who call themselves part of the resistance. Allawi's decision is a sound one and should have been taken and implemented long before now. Iraq does not need criminals to defend it.
Wisam, Basra, Iraq
From BBCArabic.com: Since when has the hospital in Falluja been a strategic place, so much so that it became the first area to be taken over by the Americans?
Younis, originally from Falluja, Iraq
From BBCArabic.com:I am originally from Falluja. I support the government in its use of force to rid us from the terrorist gangs that have been wrecking havoc in my city and causing pain to my people. I say to Arabs outside Iraq: Please save us your comments because you don't know the crimes that have been committed by these gangs under the guise of religion and resistance.
Ahlam Jamil, Iraq
From BBCArabic.com:I agree with Allawi's decision to attack Falluja. In fact, he should have done this much earlier, when the kidnappings started in Iraq.
Jaafar Al Jabri, Iraq
From BBCArabic.com: If Saddam was now in power and decided to launch such an attack against an Iraqi city, I wonder what Bush and Allawi would have said about it?
Sattar Saeed, Baghdad, Iraq
After reading the comments on this page, I say to everybody who supports Allawi and the US army - you have closed minds if you think this will bring a free life for our people. Everything's going according to Sharon's opinion of the Middle East and George W Bush is the player - this is enough to say the result of Iraq crises will be worse than Vietnam.
Dawood S Alani, Baghdad, Iraq
From BBCArabic.com: Falluja today is becoming the voice of freedom, justice and sacrifice in Iraq, as the south of Iraq was once, when it stood in the face of the tyrant Saddam Hussein.
Mohamed, Nasiriya, southern Iraq
From BBCArabic.com:I blame Dr Allawi for waiting this long to take this decision. But we are with Dr Allawi in his efforts to get rid of these criminals.
Uthman Deleemi, Ramadi, Iraq
From BBCArabic.com: Imposing martial law is the right step to stabilise Iraq. The battles in Falluja are fought against foreign terrorists and insurgents.
Maher Abbas, Baghdad, Iraq
From BBCArabic.com:Iyad Allawi is not the decision maker. The Iraqi people are our family and they have every right to resist. Let's put an end to the distortion of the picture of the heroes in Falluja and all the resistance.
Luay, Baghdad, Iraq
There is no alternative to what the US Army is doing in Falluja. The city must be pacified. For months now those murderers and terrorist operating out of that cursed city have been kidnapping bombing and killing thousands of innocent ordinary Iraqis. It is surprising how people in the West have such a narrow viewpoint on this matter. These murderers bomb our schools and kill our innocent children, whilst the coalition is trying its best to build and help us move forward. It is not the coalition to blame it is not they who plot and plan these attacks.
A A Ali, Baghdad, Iraq
From BBCArabic.com:How can Iraqi Prime Minister Allawi declare martial law when he cannot protect members of his own government? And what state of emergency? What laws can he implement? Did he do anything when the Abu Ghraib scandal happened?
Ahmed As-Sumaidae, Baghdad, Iraq
From BBCArabic.com: The decision of Dr Allawi is the right one, but it came a bit late. We all know that all suicide bombings in Iraq are linked to Falluja.
Muwaffaq, Iraq
From BBCArabic.com: I do not think that this is the right solution to solving the crisis of Iraq; I think that things will get worse and the Iraqi government knows that. Peaceful solutions are the best solutions.
Ali Ash, Shamel, Iraq
I read some of the comments on this page that describe the resistance as terrorists and cowards. I say the only terrorists and cowards are those that commit mass murder with some of the most advanced weaponry on earth against an under armed, yet brave and determined resistance that refuses to bow down to the arrogance of the US war machine. Iraq is being raped of its resources and her people killed to satisfy one man's bloodlust - this isn't about democracy - it's about domination. I pray for the resistance and the people of Iraq against the occupiers.
