Rise, Bulgaria

The Second Balkan War of 1913 was an attempt by Bulgaria to gain more territory—it was displeased with what it gained as a result of the first one and wanted more. The whole Bulgarian battle plan was poorly thought out and rushed, resulting in a Serbian and Greek victory over Bulgaria. Also what contributed was the fact that Tsar Ferdinand refused to promise Russia that they would not attack Constantinople, as the Russian Empire wanted it. This led to Russia ending its alliance with Bulgaria and not helping it in the war.

However, what if Tsar Ferdinand was much more cunning, patient, and sensible leader? What if instead of rushing the attack, he instead waited and prepared for it more thoughtfully? And what if he promised to abide by Russia's demands, resulting in Russian aid to Bulgaria? What if the Bulgarians won the Second Balkan War?
