If Russia wins the end of the war means Russia is spending far less money on war, and has the benefit of brand new territories full of loot to steal. They'll have lots of money to pay back everything multiple times over.
Wars of conquest can be extremely profitable if you win.
That's why crushing Russia's economy is so important.
Is there an estimate for how much Russia has spent on war so far?
A few months ago the Washington Post reported nearly $300 billion: https://www.washingtonpost.com/world/2025/02/24/russia-ukraine-war-cost-statistics-trump-support/
The value of the land and mineral resources Russia has stolen from Ukraine has been estimated at $1 trillion or more. So a "peace" treaty would actually put them in the green in the long term. Especially if the ~$300 billion in seized assets is returned to Russia.
A _lot_ of "ordinary" Russians are profiting from this invasion. For example, it's estimated that something like 1 million have taken stolen Ukrainian houses and apartments, moving into parts of Ukraine occupied by Russia.
These Russians are war criminals and should be executed. Though if captured, they could be put to work doing tasks like landmine clearance for the rest of their lives. We forced Germans, including "civilians", to clean up after their war.
Your last sentence is a non-sequitur. Why is crushing Russia's economy important?
Obviously because 1) crushing their economy ensures they can't repeat the process, invading another country, 2) it ensures that the invasion is in fact unprofitable, 3) crushing their economy now will certainly end the invasion.
