What would you have advocated in 1941-42 with regards to Germany (and Japan)? Would you have advocated peace? After all, according to you, war solves nothing, at the end of the day you need to sit down and negotiate. Would you have rallied for Peace Now in 1941? Would you have pressed for a cease fire and negotiated settlement? Would you have agreed to unconditional surrender?
If you would not have negotiated with Germany and/or Japan, and agree that unconditional surrender was the correct approach, please explain why and how the situation today with the Palestinians (Hamas, Jihad, etc.), Hezbollah, Iran, etc. is different. All of these groups are publicly calling for the destruction of the State of Israel. All of them believe that all the territory from the Jordan river to the Mediteranean is Arab/Muslim territory and that there is no room for a Jewish state.
Should the US negotiate with Osama Bin Laden for the same reasons? If not why not?
