Link between certain aspects of basic behavioural traits
Not really.  It's possible that behavioural traits are genetic to some extent, but it's impossible to separate that from the environmental influences enough to link to specific events such as invading other countries.  Also, usually invaders stayed to colonize the country they invaded so that there was a mixing of the genes of invaded and invaders.  So even if there were links between genetics and likelihood to invade, you couldn't make the connection now between historical events and the behavioural traits of the current generation.
