The name shouldnt cause any trouble as it is the compostition of New (clearly understandable), Warsaw (a city) and Oblast (which translates from russian into region in english). Additionally, the Warsaw Pact was a legitimate military agreement in response to the Allies' rearmament of West Germany and other WW2 devastated nations, proposed by the Czechoslovak Government; so there should be no negative connotations other than it was associated to Soviet minded nations. Might I add that similar treaties existed between the allied nations (Eg: NATO), and they arent seen as bad political agreements. As for the stars, there are two types shown on the "flag" of this fictional org: the european union circle of stars, represeting union and freedom, and the red star. Sure the red star is associated to the communist regime of the USSR, but it was used as well by other nations, including the Spanish Second Republic. As a matter of fact, the Spanish Assault Guard (entity terminated by 1939) used the red star as part of its ranking symbols within its armed forces. I must add that the Spanish Assault Guard fought for the liberties of the Spaniards and defended their Constitution (2nd Spanish Republic) until the very end of the rebellion led by Franco's forces. Sure, I'll grant you that I did re-use the star with the shaking hands from the original Warsaw Pact "logo", but I used it to represent the true meaning that it was meant to have: an association of communist thinking nations to make front to a rapidly remilitarizing of West Germany and the creation of the NATO organization by the allies.
So I wouldnt be too quick to judge the symbols presented above.
