[Black Panther] Should Wakanda have stayed isolationist?

Black Panther is a strange movie which, while hammering down the need to open Wakanda, shows that isolationism is not just a viable option, but actually the best course of action.

Send brother as a spy to the USA? He turns into a black supremacist and tries to kill you. Attend the UN meeting? Boom, you've been assassinated. Let a half-breed mongrel compete for a throne? He nearly kills you and starts a civil war. Took part in the most ambitious crossover ever? Your kin torn to pieces, and the half of them still erased (even when Thanos' erasure would be nullified, killed Wakandans would stay dead).

Also, unlike in the real world, isolationism have no negative impact on prosperity or innovations with the Wakandan political system gone awry only when someone raised in a foreign culture became a king.

The only thing the should have been learned from the outside world are military tactics for protection against invaders as Ulysses Klaw and Thanos, but, alas, country's opening or not, Wakandans remain warriors, not soldiers.

There is, of course, a humanitarian angle, but I don't see how would opening a Wakandan cultural center in Oakland would help trafficked women in Africa. Not like Wakanda already helping them, of course.

I guess because while they're a lot more advanced than others, just looking at Tony dicking around with stuff would be enough to know why.

They need to, the world is catching up. The world is changing. And they'd lose their leverage once they no longer possess a large technological advantage.
