There aren't any clear indications that the government is really interested in national unity. Maybe time will provide clearer evidence of its intentions. Lets wait and see.
exactly what "indications" do you feel are lacking?
The current government is in no way like the PPP. They are a progressive group who put aside their personal ambitions to join together for the better of Guyana. They as well as their supporters saw the PPP as a racist and exclusive group not interested in inviting the opposition into governance with them while they occupy office.
The indications if not manifestations I am looking for is this new progressive government doing something very revolutionary in Guyana politics. Asking members from the PPP who they believe are capable of being part of the government to actually partake in that government. Maybe dole out a few minister positions to them. Maybe even a Vice President position since those are readily available. Show in actions that they are not as exclusive as the PPP were. That is how you address a Unity government. You don't ask the Opposition to be part of a Unity government which would render potent the machinery of descent because it is that element of descent which protects those (the general public) who can fall victim to a political machinery where all become the virtual rubber stamp of the leader.
I don't expect this to be feasible nor do I expect the national unity drive to be either. Not in the political arena. That kind of effort is best dealt with at the local civic and religious, etc. level.
