Subject: Risk of geographic diiversity
I have been suggested that a way to "move the needle" for BRK is to add foreign stocks. Their toe has been dipped into five Japanese stocks. All good and in a stable environment. A post here recently suggested they might try China and India next. Both countries have numerous opportunities. I would point out that there is an element of geographic/geopolitical risk which overlays various parts of the world.

Admittedly, I am a foreign investment junkie - with a substantial part of my portfolio (over a number of decades) consisting of foreign stock (both native and as ADRs).

I have a (proportionally) small pile of worthless Lukoil stock as a vestige of the Ukraine/Russia war. I am also leery about some Chinese companies whose shares I own. It is not beyond the realm of possibility that, assuming a trauma involving Taiwan, these arbitrarily end up on a "taboo" sanction list. A significant change in Indian politics or a flair-up with Pakistan could effect the efficacy of their equities. For that matter, it is a non-zero probability with whacko decision-making with an America-first target outlawing the ownership of most foreign shares by USians.

These are risks that I have been willing to take (despite having my nose bloodied), but are they risks BRK's shareholders would be comfortable with if management started dabbling in dark magic?
