In season 4 of Voyager, The crew finally make contact with starfleet after four years in the delta quadrant through the use of the Hirogen sub space array.We do know that the crew got letters from their families and that Chakotay and Torres find out that their Maquis comrades have been slaughtered by the Dominion/Cardassian alliance.
However, the Dominion war is never referred too ever again for the rest of the series and Janeway and the crew often speak with excitement of the prospect of getting home.Did they not realise that there was a war still on? and that there was a good chance that the federation would lose? What if the federation did lose? Would Janeway still have headed Voyager back home? Would she try to start a resistance movement against the dominion? Does anyone think the war would have been won sooner if Voyager had returned home sooner?
