Regardless of the accuracy of the claims... how much has Ruzzia paid for that gorgeous piece of real state? I mean, if you want to summarize, you would need to include how many refineries are out of service, how many radars have been destroyed, how many tons of fuel have burned, how many aircraft have been destroyed. Not to mention lives lost - my guess is that you are now getting NK soldiers for a reason. Putin may not be that confident in mobilising more people from Ruzzia properly said.
It is no longer news, but there are drone strikes in the most expensive Ruzzian infrastructure and weapons system daily. Belgorod has become a no-go place, from being a peaceful place even nice to live in. You can look at Km2, but it is a good idea to look at the dollars and people you pay for them.
Well, it seems you are finding it difficult to provide compelling evidence that this price is too expensive for Russia.
No, it is actually simple exercise. How much would a reasonable price for a km2 of agricultural land in Ukraine, full of unexploded ordinance BTW or for a town pretty much razed to the ground, again, full of unexploded ordinance and no population left?
Would you pay, let's say, 1 million? 2 million? 10 million?
What would be your estimate? I am going to give you a clue: Farmland in the US is around 1000 usd for 1 km2 and it has no unexploded ordnance and there is rule of law and people around to work it.
Let's say you have lost 1 tank for each of those 1 km2 in Ukraine (the reality is far far worse). You have paid roughly between 5000 & 1000 times the value of that piece of land. Not an excellent business.
Not only that, you are using all your economy to go to war - that is you are into a terrible business running into it with all your possessions and all the income you can muster. do you think the US does not understand this?
A completely different thing is how much that land is worth for Putin's ego. History is full of bankruptcies driven by inflated egos.
For Russia this is a security issue. How much is your personal safety worth if you find out that someone wants to kill you? How to determine the right price, not overpay and ultimately stay alive? Is it enough to start wearing body armor or should you hire a bodyguard? How much does your ill-wisher want to kill you and is it important for him to stay alive and escape justice? How happy will you be that you saved on your safety if an ill-wisher achieves his goal?
