People of Ireland! The British are foolishly trying to defend their colonial possessions in Ulster! I say we attack the oppressors! Rise against the Colonial Oppressors!
OOC: Good, now I am gonna recognise Britain as the single legitimate government of Ireland.
His Majesty's Government has no interest in the sale of British Honduras at the current time. Our reply to you is the same as to the Brazilian offer to purchase Guyana, we do not wish to sell, but would not wish this decision to cloud relations between us and hope to gain better relations with you.
OOC: The UK controls the entire Empire. There aren't any Dominions as of yet, although if the Commies will do as they are told for a second and die, then that will change.
OOC: Wait, what? Why did Brazil do that? They don't even have a legitimate claim to Guyana AFAIK. In contrast, Guatemala has a claim of some form of legitimacy over British Honduras.
A "legitimate claim"? We're in the 19th century, man. The two "legitimate claims" you need are sticks and carrots.
OOC: When going to war over stuff, yeah. The French justification for invading Algeria is particularly silly and involved something about the French ambassador's paper fan being blown away by the wind.
However, I fail to see what sense there is for Brazil extending an offer to the UK about Guyana, since they don't really consider it theirs AFAIK. Of course, Brazil is a player so my point is probably entirely moot.
All the reason he needs is that he wants it, no?
