That is my take on it too.
“I could be wrong but I think I recall reading about a treaty/agreement Switzerland reached with various countries regarding their famous secrecy laws.”
Something like 10 years ago, the Swiss joined the Globalists and ended privacy for American depositors. So there aren’t many safe places from the IRS, at least until the alternative currency trading systems are fully operational, which should be in a couple of year.
Yes, I seem to remember reading some time ago that Swiss bank accounts were no longer “secret.” And I don’t believe that old woman is innocent. I bet she’d made plans for its disposition or transfer when she dies. The holocaust is no excuse.
