During the 2010 UNGA, UANI effectively quarantined President Ahmadinejad to The Hilton Manhattan East Hotel, the one hotel in New York that agreed to accommodate the Iranian delegation. UANI launched a boycott of all Hilton Hotels properties and held a rally outside of his hotel. Responding to UANI pressure, the Hilton Manhattan East has decided not to host Ahmadinejad for the 2011 UNGA.
On May 2, UANI launched a campaign against the Millennium in response to its decision to host Ahmadinejad for the Nuclear Non-Proliferation Treaty (NPT) Review Conference. Ahmadinejad exploited his appearance at the conference to rail against the West.
