And the Uchiha lost their strongest members when Madara and Izuna died. How is it that they managed to survive up to 5 years before the beginning of Part I?

Heck think about it, if a clan is able to give birth to a man that can easily control the Tailed Beasts, wouldn't you want to prevent more from being born? The Uchiha could control Kurama through their sharingan. The Hyuuga clan were also quite powerful and feared. So much so that Kumogakure tried to kidnap Hinata to steal her eyes. Why weren't these clans hunted down?

Seriously, the idea that the Senju were mostly killed off in war sounds ridiculous given the fact that they were in constant warfare against the Uchiha and other clans (e.g. Hagoromo clan) for quite a long long time and still thrived. Intermingling seems to be far more plausible.
