I'd love to share your optimism and trust in that country-that-shall-not-be-named's self-healing mechanisms, but its system is already centuries old and based on a sort of "gentleman's agreement" that each of the powers in the state will respect the others. To make things worse, since WW2, the executive has amassed more and more power which a sufficiently unscrupulous president can use to start an authoritarian takeover. Currently, the only hope I see is that enough people are fond enough of their democracy (even if only because that's what they grew up with) to stand up for it when push comes to shove...
