The trips are organized and funded by the American Israel Education Foundation (AIEF), the nonprofit arm of the powerful Israel lobbying group AIPAC (American Israel Public Affairs Committee). AIEF was founded in 1989 “to advance the purposes of the American Israel Public Affairs Committee.”
AIPAC is widely believed to be the most powerful organization in the US lobbying Congress on behalf of a foreign country. An outgrowth of the 1939 organization “American Jewish Emergency Council,” AIPAC’s annual convention is attended by ambitious politicians from across the political spectrum (see this example; for more on AZEC, read my book on the history of the Israel lobby).
Why isn't AIPAC registered as a foreign agent?
