Ok, I'm posting this so no one will get confused.
•Anyone can attack anyone, anywhere. If you are allied with a nation, or at peace with them, you cannot attack them.
•To attack, you must formally declare war in the nation's thread. You can simply just post. "I declare war on you."
•The defender has a week to defend from your attack.
--If the defender responds within six days of the attack, they've successfully defended their nation, and the attacker loses.
--If the defender fails to respond within a week, they've fail and the attacker wins.
--If the defender responds on the seventh day after the attack, the battle is then declared a draw.
•What happens after an attack.
--If the attacker wins, they can gain parts of the nation they attacked and/or gain one city from the loser.
---If the losing nation has more cities than the winning nation, then a city must be given up to the winning nation along with some land.
---If the losing nation has less cities than the winning nation, then land
will only be awarded to the winning nation.
--If the defender successfully defended their nation, they have the right to attack back in retaliation immediately while the attacker who lost has a penalty of not attacking any nation for 5 days.
--If the battle is a draw, nothing will happen. No losses nor gains.
**added**
•To defend, the defender must reply within 7 days.
--This means either leaders, or members of the defending nation must reply.
--Members from allied nations cannot reply to defend their ally.
