Where you go wrong is that the comment you were replying to was not talking about their ability but their options. The grand parent comment said: (paraphrasing) “Hey, what can Russia do, if no one licences them software?” To which the comment you responded said (again paraphrasing) “They have the option to stop the war”.
You are not disputing that Russia has the option to retreat, you are just talking about how they are strong and nobody can force them. Which might be true, might be false but certainly is a complete non sequitur in the context of this conversation.
