And yes you are right on "Чёрт с ними" - it's an idiomatic expression, sort of meaning "forget about them, nothing we can do". The slogan actually says "Чёрт с нами", which is "with us", not "with them". Noone actually says this, so it jumps out. And remember the cabal loves ambiguity, double meanings etc.
Reading "Чёрт с нами", it sort of means "we're beyond saving/redemption, nothing can be done".
