As long as people like you and me are cognizant of the past, there is always hope. Eventually, enough people will come to the same realisations and things will shift. Especially if we keep talking about it. They have before, they will again.
I don’t know about that. Vietnam was an interesting experiment. Almost an entire country against a confusing “war” but it persisted.
I just know nobody in my family will be going off to get blown up. We will all Muhammad Ali ourselves first if required.
And that's where it starts. We can only really influence those in our lives, and that's all that really matters as far as I'm concerned.
