Great Britain. These two countries have a history of long, deadly wars and hated for each other. However, these two countries are great allies today.
Since the overthrow of Saddam Hussein (2003) and the US occupation there (2003-2011), Iraq is considered an ally of the United States and continues to receive military and foreign aid. The neighboring country of Iran, which has supplied guerrillas and other factions fighting the US, is considered (unofficially) an enemy of the United States.
Fascists.

Soldiers who sold secrets to the enemy army were often imprisoned for treason or espionage. This is considered a serious crime as it involves betraying one's own country and providing valuable information to the enemy. The length of imprisonment would depend on the severity of the offense and the laws of the country involved.
Pain killed Jiraiya because Jiraiya was considered an enemy to Akatsuki and an infiltrator to the Hidden Rain country. He knew some of the secret of Pain's God technique and was an enemy of his goals, sadly :(
