@ossobucotemp,
Columbia and Colombia are easily confused. Add in the fact that Columbus is actually Colombo, (except when he was Colón), and the hope of applying any standards at all to the name completely dissolves.
At any rate, the head of the 40 year long rebellion has said, from exile, that he doesn't intend to pursue his rebellion by force of arms anymore, so apparently the violence is over. The reason the deal narrowly failed was that the voters felt the rebels, who had killed many Colombians, were getting off scot-free. They wanted some sort of punishment.
It seems to me that with a vote this close, (the winning "No" side only got 50.2% of the vote), that some kind of modified deal should be able to be worked out to bring a small percentage of the "No"s over to the Yes column. The referendum failed, but a modified deal would seem to be in the offing.
