Marokh, and Ali, a man beside her, say they do not like the royalists, who "want the same king as before". They are hoping that Mr. Bush will bring his troops home from Iraq via Iran.
The presence at the United Nations of Iran's new president, Mahmoud Ahmadi-Nejad, has galvanised the exiled opposition into action.
Still, historical and ideological differences have prevented rival groups from presenting a united front.
One opposition group, the People's Mujahideen Organisation (known as the MKO), and its political front, the National Council of Resistance of Iran, has tried to capitalise on the obvious US hostility towards the newly-elected president and the Islamic republic's suspected nuclear weapons programme.
Both organisations are banned in the US as terrorist groups because of their alleged attacks on US citizens in the run-up to the 1979 revolution, and on Iranian civilians since then.
But the ban did not prevent many supporters from holding banners and wearing T-shirts bearing the image of Maryam and Massoud Rajavi, the husband and wife team who effectively lead the twin organisations and their Iraq-based military forces that were once supported by Saddam Hussein but are now sequestered by the US army.
Brian Binley, a conservative party member of the UK parliament, was among a handful of western politicians there to express his support for the MKO and efforts to take the organisation off the terrorist list in the UK.
"We should do all we can to ensure that the regime in Iran is defeated," he told the FT, explaining that this did not rule out the UK government's current policy of engagement.
Hedayat Mostowfi, who is still an activist but because of the ban describes himself as a former member of the Council, says: “the people of Iran will not get motivated unless you send them a clear message”. Behind him, a large screen projects a video of cohorts of young Iranian women who formerly made up a part of the MKO's armed forces, singing martial songs dressed strictly according to Islamic rules.
Nearby, a smaller group of several hundred supporters of Reza Pahlavi, the son of the last Shah of Iran, demonstrated their desire to re-establish the monarchy, though this time as a constitutional power alongside an elected government.
Mixed in were also secular student leaders who seek a republic. The rivalries between these groups illustrate the problems facing the Bush administration in its efforts to support and fund the disparate and largely ineffectual opposition in exile.
To some of the monarchists, the MKO is a cult-like organisation with left-wing Islamist tendencies that would be even worse than the current regime. A woman simply calling herself Azar from California denounced the MKO as "terrorists" and "traitors" for having sided with Saddam Hussein during the Iran-Iraq war from 1980 to 1988.
She said she was horrified that some MKO members had torched themselves last year in protest against the detention of Mrs Rajavi in France. The French authorities later released her. Azar calls herself an American Republican supporting the Bush administration, but an Iranian royalist wanting the restoration of the monarchy.
Nearby, Marokh, an MKO supporter, and Ali, a man beside her, say they do not like the royalists, who "want the same king as before". They are hoping that Mr. Bush will bring his troops home from Iraq via Iran.
