According to the dictionary, Genocide is defined as:
A deliberate or systematic killing of a group of people esp. of those belonging to an ethnic group or nation. ethnic cleansing.

Basically,it means deciding that you want to wipe out an ethnic group and systematically doing so. There is no evidence whatsoever that the Federal Government of Nigeria, during the Biafran war, planned to kill off the entire Igbo population. There is absolutely no documentation of this. The whole goal was to defeat the Biafrans into surrender from try to secede from Nigeria. So no, Nigeria wasn't trying to wipe out igbos from the face of the earth. If there was an ethnic cleansing, the picture will be totally different.

If you want to call Biafra war a genocide, then by extension, there is also a genocide going on in Iraq, Syria, Afghanistan and anywhere else with a war or blockade going on. We all know this isn't true.
The Biafrans had the option to surrender. They were encouraged to surrender. But deciding to "fight to death" unfortunately makes it a suicide and not a genocide.
The biafrans died for trying to secede from Nigeria. Not from an ethnic cleansing like they like to claim. wtf.
war is always brutal and the Biafrans knew what they were getting into when they declared war.

In most nations, when a group loses a secession war, the leaders of such group are punished by prison sentences or death. Ojukwu and his men were pardoned which is very kind gesture on the part of the Nigerian govt. Biafrans should be thankful for that.

You aren't going to be paid or flattered for losing a war. What did you expect, a celebration party?
You start a war and expect to be pampered with food? What exactly are you whining over? It was a WAR. get over it.

That's why in a war, there is an option to surrender.
In an ethnic cleansing, there is no option to surrender. big difference

besides, from the pics, all the biafran soldiers (including Ojukwu himself) look very well feed during the war. They were stealing food from the people they were supposed to be protecting.
