If I were involved in a legal suit with Bill Gates, and if he were really intent upon winning - even by using "unfair" means, such as forcing me to spend more money for my defense than I can afford - would it be intelligent of Gates to spend a mere $5 million (chump change for him) to force me to spend $50,000 (a fortune for me)?
The countries belonging to NATO have a combined GNP many, many multiples of Russia's.
If we could dump $1 trillion in ordnance on Russia's military assets, and succeed in destroying a mere $500 billion worth of their assets, we would bankrupt them - with ourselves barely breaking a sweat in the process.
This is how you attrite your enemies, win wars, and safeguard the peace.

You speak as if NATO will remain engaged, and commit whatever it takes to defeat Russia in Ukraine.
Yet you know that will not happen.
