After Napoleon and before WWI, Russia was involved in one military conflict with major European powers...
Yes, you conveniently forgot to mention that we lost the Crimean War to a coalition of the Ottoman Empire, France, UK and Sardinia-Piedmont.
So Russia lost a war that it had fought against 3 empires and a rump Italian state simultaneously - big whoop.
The fact that it required pooling the resources of nearly every other Great Power to simply fight Russia to a standstill around Sevastopol should be telling.
I don't know if history about Napoleon is only taught in Russia until 1812
Within a few weeks/months of Napoleon's retreat from Moscow, the Imperial Army was clearing Lithuania and the Duchy of Warsaw. By Spring, Russian forces entered Prussia, and continued advancing westwards.
At this point in time, Prussia was effectively dead - and Austria completely demoralized and depressed.
Retaking Poland and clearing the French out of eastern and central Germany was the main factor behind the resurgence of the coalition. There would be no more coalition wars, if we simply kicked Napoleon out of Russia and called it a day.
The general mood in Europe was defeatist even after Borodino, and many of the allies were seeking to find some new accommodation with Napoleon.
Instead of just defending our own lands, Russia became the main advocate of driving the war to a total and conclusive end.
Russian manpower was central to later coalition armies (spread throughout the entire continent, not just present at a single battle like Leipzig). The Russian emperor became the central coordinating force of the entire coalition.
In brief - in everything that happened after 1812 - Russia was key.
The Russians haven't underwritten anything, even during their brief stint as a superpower
Your hate for Russia is blinding.
1) Russia co-founded the modern global security architecture, along with the United States.
2) Through becoming the second state to develop nuclear weapons, and the state with the largest nuclear arsenal - Russia became the only country that could effectively retaliate against America. This "underwrote" the stability of the entire post war era, as it constrained the US ability to impose outcomes around the world through force. This guaranteed that 1914-1939 would not be repeated again, where massive states fought each other directly.
3) Through leading the internationalist and socialist pole of the world, Russia "underwrote" the decolonization of entire continents. Many countries owe their current existence, to the fact of Russian intervention.
4) After 1945, Russia acted as the main guarantor of the inviolability of borders in Eastern Europe. Yes, it came with occupation and coercion, but some Hungary did not dare to try cut off land from some Czechoslovakia, or some Romania did not dare do the reverse to Hungary.
5) Russian presence among the two superpowers, is what established the entire anti-fascist post WW2 moral order. The world - countries like China and India - would not pay 1/100th the respect to international law, if they thought the system was designed through an exclusive Anglo-American arrangement.
