What about the aria? It doesn't make sense for this independent country established by dictatorship, does it?
In order to plan crosby's independence, Dita ordered the Red Constellation to attack crosby and put all citizens under house arrest. This is not a country, but a prison, and Lloyd is fighting to break this pattern. This is not a state or country problem. People's freedom and security cannot be guaranteed, let alone a country. So Lloyd was surprised why an honest man like Arias would help them.
That's it.
