One problem I have is that when I make treaties, the F@#)#@$ computer can then send ships through my guarded warp ports, in preparation for an attack (I once had a military alliance parter do that).

As a result, I have now adopted a policy of no treaties except with neutral empires, since neutral empires won't come marching through my warp points, colonizing MY planets, etc etc etc.
