Hmm. I don't know if this speech was made at a specific date and you want us to determine the aspect that best links up with that speech for that date, or if you want us to, maybe, determine an aspect the man has in his chart that would best explain his war lust.
Also, I know that I am no astrological expert: I barely have a handle on the basic meanings of the planets and how they would interact with other planets and signs.
But, my guess is that this guy has
Venus in Aries . His overall joy during life (Venus) comes from war (Aries, obviously).
