One thing about growing up in Kuwait, is that history classes make sure you’re aware of how much global effort it takes to put out oil fires.

I think *with coordinated effort* it took a year to put out the fires from the gulf war?

War With Iran
War With Iran YouTube video by Big A

A decent primer on the longer history of the UK, Iran, and the U.S.β€” how we continue to not learn and the wild origins of BP that I wasn’t aware of.

3:30 am me - reflecting on how I’ve chosen a career where I’m genuinely intrigued why one very large matrix and another matrix are slightly different β€” when they should be the same.
