Why on Earth would the Clintons still be friends with Kissinger if Nixon and Kissinger did actually sabotage the Paris Talks? ... That's my big flaw with that theory.
If anything, this is further confirmation of your theory? Even by the standards of politics (with all the vice, deceit, and manipulation it involves), the Clintons are a top contender for the most ghoulish political couple of 20th-century America. To borrow from Christopher Hitchens (I recommend watching the whole interview), Bill Clinton in particular can be aptly described as an "unusually ghastly" individual and the textbook case of a complete and utter psychopath.
The likes of Nixon and Kissinger are precisely who you’d expect the Clintons to keep company with.
Utter nonsense.
President Clinton may have been one of the most dishonest politicians about his private life (at least until Donald Trump, George Santos and Andy Ogles came along) but both he and Hillary Clinton are documented to be two of the most honest politicians about their public record, public dealings and public policy.
I could care less if politicians lie about their personal life. I care more about the job they do.
I'm not sure what Christopher Hitchens' interview specifically is being referred to, but I'd guess it was during the time that he was being his usual bombastic and obnoxious self in defending George W. Bush's illegal invasion of Iraq. I'd don't think Christopher Hitchens should be taken as a credible source on anything, and certainly not when it comes to identifying psychopaths.
South Park mocked the notion that to Americans anybody with a British accent is an intellectual, and certainly if you take away Hitchens' British accent all you're left with is a bombastic and obnoxious person.
1. Broken clock.
2. Hitchens was largely vindicated with what he said, pretty much until 9/11 which scrambled lots of people up
3. South Park mocked climate change and Al Gore, they're not a more reputable source than Hitchens just because they have Eric Cartman saying strange things.
