What if Russian Tsar Nicholas I would have concluded that Austria is likely to be an ungrateful friend to Russia and that it's thus in Russia's best interests to support Hungarian independence in 1848-1849? What would the effects of this have been? Obviously the Crimean War might still occur on schedule, but would Austria have used the Crimean War as an opportunity to try reconquering Hungary by force in this TL? And would Austria have actually succeeded in doing this? And if Russia loses control of its Hungarian puppet/satellite state, might it successfully demand compensation elsewhere, such as in Wallachia and Moldavia (the future Romanian Old Kingdom territories)? These territories were already occupied by Russia in the early and mid-19th century, after all.
Anyway, any thoughts on this?
