On the legitimacy of refusal

Hello Rabbi,
I remember that you believe that it is legitimate to resort to the tool of refusal as part of the political game, and that this is how the public expresses a position. On the other hand, I have heard many experts claim that refusal is a dangerous tool that should be reserved for at most the most serious cases of clearly illegal orders, and certainly not as part of the political game. I wanted to ask why, in your opinion, the danger of refusal does not outweigh its benefits. And especially with regard to the refusal of pilots today, why, in your opinion, this is legitimate refusal and not an excessive step.
