AIPAC
The American Israel Public Affairs Committee – linked to the Conservative wing of Israeli politics.
For more than half a century, the American Israel Public Affairs Committee has worked to help make Israel more secure by ensuring that American support remains strong. From a small pro-Israel public affairs boutique in the 1950s, AIPAC has grown into a 100,000-member national grassroots movement described by The New York Times as "the most important organization affecting America's relationship with Israel."
