I do not remember having the AI attack me at any of these times (this kind of thing has happened to me on no fewer than 3 occasions - landing in another's empire). That doesn't mean they didn't want to - they may have been focused against other empires that they were at war with, etc...

On the other hand, I have closed up WP's behind a 'juggernaut' fleet (close off WP's so no diplomatic relations) and the AI continued to be hostile. Go figure....
