I tend to agree with myths #8 and #10. These points need to be carefully interpreted, though. Many people draw wrong conclusions.

The other myths seem to be deliberately made up to discredit those who hold similar but not identical positions by manipulating those positions into something that's wrong.

#6, #8 and #10-12 are not really about warfare, but about politics and societies.

I remember Peters as someone who does occasionally throw some interesting point into the public discussion (albeit not often something I'd agree to).
I also remember him advocating some quite barbaric and xenophobic ideas.
He's certainly no-one I'd recommend for negotiating/mediating in a complex conflict.
