Here's a thought. What might be some impacts of humans in power taking a more "robotic" approach to leadership?

As a case study, let's consider foreign interventionism.

What if we had a President who set forth objective criteria in dealing with all foreign powers?

Example:

If actions by a foreign government result in the deaths of 1000 people, we officially condemn those actions.

If they result in the deaths of 10,000 people, we institute diplomatic/political sanctions.

If they result in the deaths of 100,000 people, we intervene by whatever means are deemed relevant (invade, bomb, etc.)

...what might happen? I think the obvious first answer is that the places in which the forces intervene would look quite different than they do today. What else might be some impacts of decreased subjectivity and increased predictability in foreign affairs? Thanks in advance to all who weigh in!
