(I hope my attempt to italicise worked.)

By "slightly downgraded accommodation", I assume Teribus means America's torture chambers in Guantanamo Bay?

You may indeed be right. It would be interesting to see the effect of America turning its torturers on Irish people, with an estimated 40 million Americans being Irish-American. Way to form an internal enemy, man!
