There was never an ideology to not serve as a minister.I cannot guess, but I can wonder what the Torah Council of Sages will decide. The main principle is though that it will be the Moetzes that will decide and not me nor Litzman.
One must also offer a good word for a person who does not want to be a Minister for ideological reasons and is willing to accept the decision of the gedolei torah and not decide for his personal career.

first he says there is no ideological reason behind it, and then he praises Litzman for the ideological reasons of not becoming a minister. which is it - ideological or not ideological?
