Emperor defense question

[Gliese 581]

If your neighbor is pleased with you and they attack is for one of 2 reasons usually:

1. Your power is much lower than theirs and they see you as an easy target.

2. They have nowwhere to expand to.

In case 1, you should have kept your power higher.

In case 2, you should know they will attack before long, and build more units.

Solution to both cases is to build more military, specifically more siege units, and when the war comes, be the attacker with your siege units, not the defender.

I agree, but I think there's a third reason. The leader happens to be mentally unstable (Shaka, Monty, probably more). If you get a psycho next door you need to have him at friendly unless there's a more tempting target around for them to play with.
