My Portuguese isn't great, but I believe this says something along the lines of "maybe it wouldn't be bad to follow Trump's example and decide our own destinies!"
Your Portuguese is quite good actually!
Yes, what they are saying is that Angola should make their own choices and don't give a crap about what Portugal or the world thinks. Just like Trump. Although in the rest of article, they say Trump's victory was a fraud because Hillary won the popular vote.
But this statement is ludicrous and so hypocritical. In reality Portugal doesn't want any change in Angola, on the contrary. The daughter of the President of Angola, Isabel dos Santos, is a shareholder in many companies and banks in Portugal and in some cases she has the majority of the shares so, any change in the government in Angola would be bad news for Portugal.
