What is the reason that Buffett said his company might 'own this stock forever' when talking about Occidental Petroleum?

I made a post asking about this stock back in January (cross posting now allowed) and Buffett was still underwater on this position back then. Well he's not under water any longer!

To explain the title, he made a remark in one of this shareholder letters that said Occidental might be a stock his company "owns forever".

No, I did not listen to Buffett's wisdom back in January. But I can't help but wonder what kind of insider knowledge he may or may not have had leading up to the war in Iran...

Thoughts?
