I mean, if, by "fighting back", you mean destroying its own economy, then yes, The West is "fighting back". But not the world, as the vast majority of nations - 7 Billion people -- are not imposing any sanctions because they have more rational leadership than in the 1 Billion people that are destroying their own economy in the name of "fighting back".

The main reason why the West is in rapid decline at the moment is because it is adopting policies based on their therapeutic value to the administrative class, rather than their effectiveness. That's a recipe for failure, and if you want to succeed rather than fail, then you need to choose your actions carefully and strategically rather than slamming your head against a granite wall because you think this means you are "fighting back".
