Bar-en-Danwedh
House of Ransom
the elves would have mooved a little faster to valianor, the men that didn't surrender and join Sauron, would have been killed or driven into hiding, The Mouth of Sauron would have taken over orthanc and destroyed the ents, and Saruman and Wormtongue would have been hunted doen in the shire and killed by Saurons forces. Once Middle Eath was under his controll, Sauron would have gathered all lost Allies hidden and scattered in the earth like the balrogs and what dragons may be left deep in any moutain or cave, and massed an army to launch an attack on Valianor, and retrieve his master Melkor from his bonds in the abyss!!!
then some sort of 'booze-up' would have been in order i suppose.
