Well,as a Nigerian, without any doubt,my best president in Nigeria is late umoru Musa yaradua.though he didn't last long, but his policies where good eg(the seven point agenda)
It is very good and commendable that you are proud of your president. I live in Ukraine, we are not having the best times now, but our President Volodymyr Zelensky is steadfastly enduring all tests. I am proud of our strong president, our independent country.
