so, I am a military planner advising the commander in a (just) war with Niatirb. I am also a Kantian who regards intentionally killing the innocent as always wrong. I need help figuring out which guidance would work best in this situation.

One of our vital objectives is to take out a nuclear reactor in the countryside of Niatirb. The reactor itself is a legitimate military target of significant strategic value, but the Niatirbian dictator has surrounded the plant with 100 involuntary "human shields." The plant cannot be destroyed without killing them.

I need help figuring out how to consider the principles of discrimination, proportionality, and double effect. I can stipulate additional details.
