Unlike when they instantly came to Cardassia's rescue with military force when the Klingons threatened to invade.
In fact they came to Cardassia's rescue twice.
Weren't they asked for help, though? It's my understanding that if another goverment asks for Federation aid that they're allowed to step in and provide whatever asisstance they can. Dukat contacted Sisko to ask for help in getting the Detapa Council members to safety. I suppose Sisko could have said no, but that's not Starfleet's style.
