It is inspiring that you had arrived at a similar conclusion as myself.
Haumea appears to actually potentially be very violent, especially if conjunct to Mars. Haumea appears to represent unity and compromise, rather than peace per se.
"Why can't we all get on" is the essential cry of Haumea. This does not preclude an attempt to establish 'order' through force it would seem.
Haumea in both cases deals with connections between divided things. In 15 BC it represents connection between God and Man in Christ and in 1954 it represents the increasing interconnectiveness of the entire human race in the age of MAD and the Cold War.
