I agree with your point on Libertarians, but am less-enthusiastic than you about the idea that we can have "less-benign airbags" in this U.S. system; especially the example of Putin. Not that he's a great guy, he's a piece of garbage, but the "benign female leader" we're soon to elect has made more than her fair share of overtones along with Robert Kagan/Victoria Nuland/NATO that she's ready to attack Russia by virtue of them being Russia. I think the knowledge of Putin that we have great nuclear capability is enough to allow us to be "Hobbit-like". See: Cold War 1945-1991. As far as protecting us from other powers, that idea is a farce; the only thing we have to protect, at this point, is our hypocritical exceptionalism.
Also, the quality of being benign amongst our elected officials would be much more possible if we were allowed to use an instant runoff system of voting and had paper ballots, as we see what happens when these machines falter or have questionable results: no paper trail! The Brexit vote at least had that going for it.
"...she's ready to attack Russia by virtue of them being Russia."
A bit overwrought, methinks.
Take a look at the map and the giagantic land mass that is Russia.
And yet we see him probing and pushing and sneaking his little green men wherever he sees a weakness.
And we have long seen him closing down their free press.
Talk about corruption! There's ya feature!!
H. Clinton was wrong about invading Iraq, but then most of us (Americans) were.
She has no illusions about Putin being a cool guy we can trust--I'm good with that.
"As far as protecting us from other powers, that idea is a farce; the only thing we have to protect, at this point, is our hypocritical exceptionalism."
I agree about the exceptionalism.
But about the need for protection against the likes of Putin, ISIS, China (encroachments in China Sea,
for example)...not a farce at all in my view.
