Suicide bomb question from a muslim?

I am a muslim and from the islamic texts i have read they all say that suicide is haram or forbidden in Islam and that the only way that comes close is if you go to fight to protect the innocent or defenseless knowing that you are going to die, i need a muslim who believes in suicide bombing explain how it is halal or permissible in Islam i am not saying it is haram or halal i just want to know what both sides have to say about it i heard the argument of the side saying its haram now i need the argument of the side saying its halal
