Diplomacy has its strengths and weaknesses which is why you feel that yoruba are unreliable and cowardly. The reason while Nigeria has not broken apart is because of the yoruba tribe. We can't do what igbo wants us to do and we can't do what the hausa Wants us to do but what we feel is the best for us and the nation at large.
We are like the chief corner stone, silent but powerful. It doesn't matter if you like us or not whatever we do or supports succeed.
It's normal to have your grievances and we all do against other tribes as well.

NB. No tribe is perfect we all have our weaknesses.
God bless Nigeria.

Nigeria is a piece of joke.
same people reshuffling themselves over and over, same people that has been there and offered nothing
