Where is it defined who or what an infidel is?

in the muslim belief,killing oneself is infidelity.but according to people who are defending their country such as palestinians who set off a self bomb among israelis for instance,its martyrdom.as they are dying while defending their honour and land,its not mainly based on islamic beliefs,its the universal belief of sacrificing for the bigger cause,and in this case,freeing your homeland is bigger than you own life.exactly like soldiers who enroll in the army to defend their country,and if they die in action they are considered war heroes,why is there a difference?these soldiers know there is a great chance for them to die during the war,so does that make them suicidals or murderers of themselves?on the other hand,people who set off bombs among civilians like what happens in iraq or any other country,blowing off embassies and airports,this is not a right path of islam,at least according to the moderate muslims.and islam,like any other religion,has followers who take matters to extremes and then the blame goes back to the main concept,even though it has nothing to do with the extreme actions and practices of such followers.and i really want to stress on the fact that there is no script or part of the islamic religion that urges the muslims to kill the non-muslims(the infidels).the islamic religion is to be spread by kind words and logical persuasion and discussion.and again the fact that some extremists tend to try to spread it by force,doesnt mean that that was the regulation or guideline provided by the main islamic mentor prophet Muhamad peace be upon him.and there is nothing that says the Americans or the British are infidels,we are all to live in peace together and muslims are to spread islam in a peaceful,cultured and logical respectable manner,without any offence to any other religion or belief.and to make the picture clearer for you,id like you to know that during the time of prophet Muhamad (pbuh) whenever there was a war or a battle,he'd order his soldiers and commanders not to hurt children,women or old people.and never to destroy a house or synagog or church or any place of worship.and whenever there were war captives they were to be treated with respect and care.but then again the fact that some muslims do not follow these guidlines accurately,isnt a fault of the islamic religion itself.as a matter of fact,a part of being a muslim is to believe in all messengers and holy books,starting from Adam till Christ who was the last prophet before prophet Muhamad,and muslims are not to demean or offend the other religions or prophets.as for the reason behind the anger towards the "British" or the "Americans",it is that on one hand,they are sending out their soldiers who are killing people in afganistan and iraq,civilians who are claimed to be linked to terrorists,even though the main "reason" for them to start this war was that the fact that there were weapons of mass destruction or nuclear weapons or wtvr there,which by the way have not been discovered yet.on the other hand,the British & American governments support israel and its acts of violence and mass murders in palestine,lebanon & syria.so,i hope i gave you a clearer picture about what you wanted to know,and if you have any further inquiries feel free to contact me.i hope i was of help to you.have a good one
