At this point I imagine that the Justice League must have some sort of deal that dictates, barring the odd world-ending crisis or opportunity for a profitable crossover, that they have to deal with whatever problems are occurring on their home turf alone. Flash stays out of Gateway City; Wonder Woman stays out of Metropolis; and Superman stays the hell out of Gotham. That's just the rules.

Otherwise, I think Clark may have received an angry offscreen 3am phone call from Batman demanding to know where the hell he was when cops, soldiers and civilians were being massacred on the streets of Gotham while he was starved by a blood-bathing weirdo to the point where he was desperate enough to steal picnic baskets like Yogi Bear (a reminder that last part actually happened).
