I'm pretty sure it's actually quite a big bit of diplomacy, but I agree inasmuch as this wasn't a situation where you have to patiently wait out the bullshit to find things you agree on, this was just propaganda and trying to justify an illegal invasion.
I agree largely, but listening to a carefully nuanced and selective version of the truth may well be diplomacy. Listening to blatant lies and having someone take you for a total idiot isn't, I would hope.
No. Listening to lies and bullshit isn't diplomacy.
