<p>There was that leaked video of a Cambridge Analytica exec bragging that they came up with the handcuffs in the Crooked Hillary meme. Except that was hardly a big thing. The phrase Crooked Hillary was arguably “linguistic killshot” by Trump; CA’s little riff on it was insignificant - and that was them trying to <i>sell</i> their services with their most impressive feats.</p>

<p>Well under Dubya it was pretty successful. Firstly, there was never a repeat of 9/11. Secondly, they pulled off one of the most overwhelming military victories of all time against Iraq, a full-blown invasion completed in weeks with hardly any losses. This also secured Israel’s long term prospects in the region, which seems to be one of the most sacred directives of American policy. It did also lead ultimately to civil war in Syria and political destabilisation in Germany/Europe (from refugees), but that is no skin off Uncle Sam’s nose. You may not like it, but in the history books that’s what peak foreign policy looks like.</p>

<p>> “deeply off the rails”<p>How sheltered are you people? Scott Adams was a pretty standard non-woke boomer. Do you think that just because you don’t hear certain opinions in the workplace or the faculty or the Atlantic podcast, that they aren’t widely held by members of the public? Do you think everyone’s into DEI, BLM, trans-rights, multi-culturalism etc?</p>

<p>I kept meaning to tune in again to his livestream before the end. It was always a good listen as he went over the news with his dry sense of humour and judgment on fact vs fiction.I liked how he kept going after they cancelled all the Dilbert syndication - good lesson in resilience. RIP.</p>

<p>According to the paper you posted (interesting analysis), it’s not just low-vol assets, but good quality ones. Also, they would no doubt do a lot more buying of undervalued (good quality) companies if they weren’t by this point “too big to care”, so to speak.</p>

<p>When people say undervalued in this context, they usually mean it has a low price to earnings ratio. Intel is definitely not that - although it could still be a good bet if you have reason to believe their fortunes will greatly improve in the future. But it wouldn’t be a Buffett target in its current state.</p>

<p>Not quite right. The pivot was from good companies at a great price to great companies at a good price (unless you can get a great price, but that’s unlikely).<p>Over the long run the latter is a better and more scalable strategy.</p>
