Having the mind to stop corruption is not easy in a nation that corruption is seen as nothing, making an attempt to do so some politicians will do everything to frustrate the agenda. Do you think a genuine president can easily end corruption of this level ?
This is almost impossible except by the grace of god, if not there is nothing you can do to stop corruption in a country where 90% of the politicians is corrupted if they see that you are directly or indirectly trying to deprive them from what they have been getting before they will just team up and start looking for a way to bring you down, and yeah that's how it is. That is why I don't like engaging myself into all this politics of a stuff, moreover politicians is not always sincere and honest in all thier dealings so this corruption is just running through thier vain.
Is only a genuine president whose power supercede every other powers that can be able to put an end to corruption in such country, without this there is no way it will work.
