Can't believe I never considered this question earlier. In the years that Wakanda supported the ANC, did they also give support to Winnie Mandela around the time of her alleged crimes?
Depends, if T'Chaka was running Wakanda during that time he might very well
have supported the evil B.S. as long as it A)suited his purposes to do so and
B) Stayed out of Wakanda.
T'Challa unlike his predcessor actually gives a rat's ass about what happens
outside its borders. He'd of cut the money and support off right quick.
