Ok, if you want it spelt out, the logic would be something we all learnt in grade school. The only language bullies understand are consequences. Putin annexed part of another sovereign country in 2014 and faced no consequences. He therefore launched a full on occupation of the same country in 2022.

Also, there is no need for ad hominem attacks. Contrary to what you might think, they don't actually serve any purpose in putting your point across.
