You know, sometimes it's easier to read the tea leaves than others.
When a nation is so very screwed up it engages in vendetta-style raids against those trying to tell the truth about that nations economy, and predict said nations credit-worthiness based on their best understanding?
Yep, that nation is well and truly screwed, and merits immediate de-rating as force is now triumphing over law. Nobody is safe, and credit extended to such a nation is only as safe as the next whim of the ruling solons.
Bad risk, do not invest.
Great food there, though.
