Agreed.

Agreed.

In addition, we should fix the situation that I and Greg on irc yesterday
dubbed the 'LLH' problem. It stands for love-love-hate, which is best
illutrated with players A, B and C who have alliance(A, B), alliance(B, C)
and war(A, C). This situation leads to lots of ridiculous circumstances.

So the new rule we came up with is: When declaring war on a player, you
also declare war on all his allies. (If they were also your allies, too
bad.) You cannot enter into an alliance with a player if you are at war
with any of his allies.

The bomber is always the best defender, since it cannot be attacked and
hence cannot be defeated.
