Islam will always be at odds with judaism and christianity. Why? Because IT REPLACES them.
So there will always be a certain tension between the religions. It is an odd situation. You are in a room together and the Prophet Muhammad is claiming to have been sent by YOUR GOD.
But you don't think so, meaning you think he is a liar. So this is clearly not a working situation, where you are in a room together and one party thinks the other is a liar or deluded. Christians and jews TOTALLY don't believe islam is from THEIR GOD.
How can you form an ALLIANCE as religious entities, when you think your partner is FALSE? Its impractical. Totally totally impractical.
Muslims atleast believe that Jesus was divinely inspired and judaism was originally a religion from Allah, but jews and christians TOTALLY do not believe that Islam has ANYTHING to do with God.
As another answer indicated, we don't consider Christians enemies, unless they are of a direct threat to Islam. I personally, and I can't speak for all Muslims obviously, but I respect Christians a great deal and I really appreciate anyone who is steadfast and pure in their worship of God, whether it be through Islam or another religion. I appreciate your interest in Islam, which is indeed a very pure, tolerant religion at it's heart.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
