Interesting points but remember they aren't targeting the underworld they are targeting just the Gremory group.


 * They don't have to take on the satans which is where politics come in now although Sirzech does have a sister complex with Rias, he believes in her to be able to deal with her own problems, and besides he would be busy trying to clear off Grayfia's name so he would more then likely allow her to deal with them and see how things play out.


 * Next is the whole getting over powered by the entire underworld they are not trying to get revenge on the entire underworld just the Gremory team meaning with enough man power and with Euclid seizing an opportunity like this to hurt his sister, by taking out someone dear to her, and even if Euclid is out which I doubt there we have also heard about high ranked angels being loyal to the khaos brigade. These high ranked angels would probably be somewhere at the level of Kokabiel and this may become a major problem for Gremory group
