Congratulations on your freedom from the rule of your Dear Brother. Every man has an ego, but no man's ego should rule a nation.
I have two suggestions for you:
First, I hope that you reform management of your fossil water (The Great Manmade River) so that it's used more efficiently and equitably. Call me -- or read my book -- if you need help on that.
Second, I suggest that you take the biggest problem -- money -- off the table immediately, by promising to distribute oil dividends to citizens. Iraq's problems with sectarian jealousies have been fueled by greed over its oil wealth. Read this post for more.
Best of luck!
