All three are searching for a complete truth, not a diversified pool. Unfortunately, by the time one has worked their way down to common-tenants, the religions are right back at the theological starting line (albeit they would be monotheistic and not poly or wiccan).
Since they cannot go backwards, they must look forwards, and we encounter numerous roadblocks - some of which include:
Judaism/Islam cannot accept Jesus Christ as the son of God.
Christianity cannot accept Muhammad as true prophet - and cannot accept Judaism as it would be like taking a theological step backwards.
Toss in the other issues, the type of differences in belief that split each of the three faiths into smaller subsections - and we see that there is not all that much room for compromise... the three have spent over two-thousand years crystallizing, arguing with each other and with themselves... and have reached a relatively steady state.

The wars themselves, I feel should be split into at least to classes - those that were truly religiously motivated, and those that simply carried the victors religion along, as victorious cultures had always done... I think we should also note that in many cases the spread was peacefull, as was the initial case of Christianity.
