In any situation, in a war between the Uchiha and the Leaf, it'll lead to Itachi fighting with his comrades and losing his own Uchiha comrades, that will indeed bring an MS into them.

Strategy wise, the Uchiha could use the Ninetails, if things goes out of hands, or sought help from the obvious enemies of the leaf, that will be in favor of allying with the Uchiha, like Orochimaru, Obito and Akatsuki. They all operated for different means but all of them have a common enemy and can have a interest on the Uchiha. Not that I'm saying they will call them for help, but it can happen.
