don't you think accepting foreign intervention is the way to go

No, I do not think so, it does not matter whether it is a failure or not. That's what democracy is all about. You have to take responsibilities for your actions, otherwise, when are you going to learn from your mistakes? This has been the history of Venezuela all over again, we have to go through so many fail states and we have had so many overthrown that this is something very common. I do not care and the majority of Venezuelans do not care whether we are a failure or not. The problem is ours and no one should have the right to tear down our country just like the middle east. You don't even understand and I think you have to read more about international law, UN charter and also history. Interventions are proven to be a wrong measure to take. It just ends up creating migrating problems, destroying, even more, the country and its political institutions.

People advocated change, civil war started, many lives were lost, but wouldn't you argue that this sacrifice has lead to more peace and stability in the region?

Because it was the US itself who decided to tear down the tyranny of the British empire, it was neither Mexico nor Canada who confronted the British Empire it was the US. No one else.

Blacks now have the human rights they deserve, as opposed to those in the past.

After 160 years of oppression and not being recognized as full citizens of the US? going through lynchings, massive violation of the human rights, and Racism? I think you are being very naive with your point of view, and this is clearly due to a lack of understanding of history. I would recommend you to read more and to dig deeper into this intervention and the US history and its foundation.

I think while its an ideal to achieve, Venezuelan could be much better off with a foreign aide, instead of pulling itself into a deeper problem.

But then you are violating the right to self-determination, the soverengty, and the will of the Venezuelans who elected Maduro.

While foreign intervention might not be successful, I think that doing the same and not changing anything is an even worse solution.

Dude, I think, and seriously you have to read more about the middle east and the harm caused there. I'm leaving you some documentaries about foreign intervention and its results.
