No.

And our population has been so propagandized that they don't know why...

The USA is a collection of sovereign states. At least it was when it was formed. Some states have referendums. Others do not. This was a defense against direct democracy and some of its risks. Tyranny of the majority.

But is a national vote a solution? How does this resolve conflict better than state by state referendums? IMO most Americans are self centered but they are propagandized to care what people on the other side of the country can or can't do. Instead of leaving their governance up to them, they want to force others to do what they believe is right.

Its odd to me how someone can oppose a government forcing its will on another country across the globe but be just fine doing so in the US. I never get a logically pleasing response to this.
