This is a classic "that never works" maneuver. The USA did the same thing to some extent when it "de-Baath-ified" Iraq, which shows that this is a thing that doesn't work regardless of whether you are "left wing" or "right wing" and it doesn't even work when the USA does it. It also sometimes fails in the corporate world, such as when an "activist investor" replaces everyone who knows what they're doing in a company or a lot of people are fired in an acquisition.
