Put it this way: neither side is backing down. Calling out the Uchiha means their defeat because the Hokage would flatten them.

Not calling out would mean the village's defeat because the element of surprise turns the tables.

Open civil war could result in more casualties because you'll have to kill off the entire Uchiha clan anyway, while the village loses their warriors too. Such an unstable internal power struggle would also invite external invasion from enemy nations.
