Wasted resources? That is what storage facilities are for. I almost never build WP or sats unless a planet is immediately threatened because 99% of the time they will be useless and will waste resources as bad as letting them dissapear. OK sometimes I do bring sats up to the front lines but most of the time my front line moves as fast or faster than the transport ships so thats not even an option. If an AI ship gets into my home system after the first year I would be very surprised.

The easiest way to stop this problem is to not make treaties. They don't Last long anyway because of the Mega evil empire setting and you can't keep them out of your systems if you are non-aggression or above with them.
