In May of 2005, the Andorran government declared war on Latvia, saying it was angered that Latvia had turned into a nasty offshore tax haven. According to the news outlet Spanishmedia, the Andorran Ministry of Defense was quoted as saying:
‘We decided to declare war on Latvia because we do not understand the culture of this country and cannot feel safe about it. By the autumn we’ll finalize the plan of war and route of intervention."
The reaction of Europe, rather unexpected by Andorra, was very cool. The European Union Parliament scheduled a session to discuss the war declaration, but that session wouldn’t happen for another 8 months.
Strangely enough, Albania expressed a desire to support Andorra, but then swiftly changed its mind.
Germany and Poland closed their airspace to Andorran fleets, though Andorra has no air fleets of its own. France and Spain, which border Andorra, ignored the entire thing. Latvian authorities had no comment.
Anonymous sources said later that the entire war declaration was a PR stunt designed to get media attention for Andorra, in order to try and boost the tourism industry. It failed.
Nobody even remembers it and most of people dont even know it
Andora is probably bigest fail of Europe, maybe second after Albania.
