You must be joking Mr. Klaus, Palestinian terrorists operating within Iraq? I havent seen any evidence for this may you point to it I think it would be rather startling.
We cannot just kill terrorism away, that is ignorant. What can be done is utter destruction of the infrastucture and leadership of the terrorist organizations which prevents them from acting, in addition to a very strong attempt at a political solution with the PA, if a peace is attempted while the terrorist groups still have the strength and potential to launch attacks it is easy for them to derail negotiations but if they are rendered impotent then there is a better chance of political success and once that is achieved all the issues of terrorism will just melt away.
Again I am not saying a government should kill civilians to save others, I am saying that to save civilians you have to conduct millitary operations and these things do lead to civilian deaths. The point here is that fighting terrorism is worth it. Most anti-terrorist operations conducted by the IDF kill or capture terrorists, civilians do get killed and that is a sad fact but remember they are used by the terrorists as protection, they are unwilling human shields who are placed in the firing line by those who use them. I will give you this link to a page of statistics that breaks down the casualties on both sides since the second intafada so that you may see the numbers of people killed, who killed them and how they compare, there are a few surprising figures there.

In regards to the personal element about killing innocent people to save others I will not beat around the bush, I would do it. As much as I am loathed to think about it if I was given the oppertunity to shoot down one of the planes on September 11 filled with innocent civilians I would do it and would kill hundreds of innocent people by my own hand, this is the tragic thing about terrorism there is no easy way out, there is no way out that wont result in deaths, no magic wand that makes it all better and we can just go along with our lives in bliss, if you can minimise the suffering by taking lives then it must be taken. These people would have been killed by the terrorists in any event, they are the victims of terrorism even if it is not the terrorist that kills them. There is never a happy ending for terrorists, if my family was on the line and was murdered by my government in a simmilar situation, or if they were walking down the street and were killed by a stray bullet during an arrest then I would be angry, I cannot say that I would justify it in advance, its not like I would have a choice in such a decision I can only console myself with the knowledge that through such death more lives have been saved, ahead by the numbers if you will. Now this sickens me to the pit of my soul, playing it by the numbers because I genuinely wish things were black and white, that we could defend ourselves without loosing a piece of our souls. I look around at the world and I see such virulent hatred, we have men out there who do not seek peace and freedom rather the antithesis, they want opression and violence, chaos, they have nothing to loose and they place us in the position of being between a rock and a hard place. It isn't just the gore that hardens my view of the world, I look at the suffering, to see the pain that terrorists inflict upon the families of innocent people, the sheer hatred that they stir within people who should desire peace, the entire effect of terrorism is this and I know it. As much as I would lie to myself that I could never kill another person its just not true, this is a very tough situation to think about, all that joy and potential wasted in an instant, Stalin said that one death is a tradgedy and a million deaths is a statistic, that entire concept makes me sick, I think of that and I see the death camps of the Nazis, the Gulags and the killing fields, the cultural revolution and all the most evil deeds committed by men, then I try to seperate it from fighting terrorism, make it different because when lives are at stake its a different situation and different rules suddenly apply -
again really difficult bloody question - can't rationalise it, cant turn it off or turn it away, I have a strong conviction that we can fight terrorism without becoming monsters, part of doing that is facing up to what we are against and making sure that the resolve is strong, I think that the best way is this, I would never ever murder any innocent human being on purpose. I would be willing in an extreme circumstance where many lives are at risk and there is no other means of prevention take direct action against a threat even if it meant civilians could be killed. If I was on the recieving end of such a policy I would be very very angry and grief would surely change my point of view for better or worse but from where I am now I would think that such actions are justifiable if they spared others from experiencing the suffering that any victim would have.
If I may turn the question back at you, if you had the oppertunity to shoot down the planes on September 11 would you do it? Could your government kill your family to prevent a larger disaster and it still be the right thing to do?
