Greece has one of the largest commercial fleets in the world. Likely the companies connected to these ships made a deal to be able to pass. It could depend on their destination (let’s say it’s Japan) as well.

$200B is nothing, because with the petrodollar they can just print more. But losing the petrodollar would collapse the US so fucking fast. Petrodollar means sustainable trade deficit, it means they can export all of their crises and let the manufacturer countries (Europe, Japan, China) eat the inflation as they print money. No petrodollar means rapid collapse.

Gripen can also sneak up on, out-manoveur and take down F35s btw.
