Hate to burst your bubble, but the International Baccalaureate has been around since the late 60's. It has nothing to do with the UN or Agenda 21. It came from Switzerland and the international schools system. I attended an IB school in Japan that was run by Canadians. A private school, as many of the IB schools are. You're way off base. US schools could definitely do worse that integrate parts of the IB program into their curriculum's.
Just because IB originated in '68 and a "private" school in Japan uses it doesn't necessarily mean I'm "way off."
The IB Diploma Program was introduced in '48 by Marie-Thérèse Maurette and adopted/modified by UNESCO, United Nations Educational, Scientific and Cultural Organization. Thus, the UN by and large.
