It's deliberately dramatized but I don't really see it as wrong. Here's how I would (less dramatically--and less interestingly)phrase the choices.
a.) If you're sure there's a path to success and you're invested in getting there, do whatever you can to achieve that goal--understanding that one of the possible outcomes is to be told to pack your things and leave. Now. The likelihood of this outcome obviously depends on the exact situation.
b.) Accept that things are not going to end well. Do your job, keep your head down, and start seeking alternatives ex post haste. In some situations, seeking alternatives ex post haste may, in fact, involve fleeing (especially in a short time horizon such as this one) but I've certainly been in situations where the writing was more or less on the wall but more in the vein of a long ponderous collapse.
Fresh gazelle is delicious. Try not to overeat. There's a whole heard, and the pride will catch another one tomorrow. It's all a matter of perspective.
