What if Romania attacks Bulgaria rather than Transylvania right after entering WWI in 1916? The logic here is that if Romania, in coordination with Russia, attacks Bulgaria and knocks it out of the war while also having Russo-Romanian troops at Constantinople, then this would be a fatal blow to the Central Powers' war effort and allow the Entente to decisively win the war in 1917 or at least to be on track to do so. This would mean delayed gratification for Romania, but Romania would still ultimately realize all of its territorial gains; this would simply be a way for Romania to sacrifice and contribute to the overall Entente cause by ending the war faster.
What do you think? Realistic? And just how likely is such a move to actually succeed?
