You’re right of course but I think the more likely cause will be typical. A policy misstep, political scandal, protests, external factors etc. The PAP will be booted out democratically if it happens at all.
But having a party that can, during the "good times" manipulate the situation, such that during a bad time, they can still stay in power. Aka, they only "pull the trigger" after they know they'd be kicked out, thus preventing themselves from getting kicked out.
Which is why the preparations should be prevented, even against someone who seems benevolent at the time.
