Increasingly I keep being told by normies that they would “love to go to the symphony someday” and it’s starting to drive me crazy because if you want to go, you can just go! It’s not a once-in-a-lifetime thing! It’s not expensive! You don’t have to know anything! Just buy a ticket and go!

For comparison, the JCPOA ('Iran Deal') payment that everyone in MAGA excoriates was $1.7bn. The $2m-per-ship toll regime on the Strait would generate at normal traffic something like $40bn *each year* for Iran (120 ships per day at $2m per split 50/50 with Oman).
