The demonstration on the steps of the Lincoln Memorial came after a cease-fire that ended 11 days of Israel’s intense bombardment of the Gaza Strip and retaliatory rocket firing of Palestinian resistance groups based in the besieged territory.
"We are hoping to send a clear message to the United States government that the days of supporting Israel without repercussions are over," one of the demonstrators, 39-year-old Washington lawyer Sharif Silmi, said as he stood in the crowd where many protesters held red, white, green and black Palestinian flags, AFP reported.
"We will stand against any politician that continues to fund weapons to Israel. We will oppose them, we will vote against them, we will fund their opponents, until we vote them out of office," said Silmi during the National March for Palestine rally.
Lama al-Ahmad, a resident of neighboring Virginia who is of Palestinian origin, said US public opinion is turning in favor of the Palestinian cause.
"There is a huge change" going on in the US with regard to the Palestinian cause seeking a sovereign homeland, said Ahmad.
"We just want the world to recognize that we are human beings," said Ahmad, a 43-year-old stay at home mother who grew up in the United Arab Emirates before moving to the US around 20 years ago.
Silmi insisted there was now broad opposition in the US to how Israel treats the Palestinians, which he likened to apartheid in South Africa.
"People have now woken up, and we're resisting. Whether young Jews, young Muslims, young blacks, young whites, there is a generational shift. And people are working across ethnic groups, racial groups, to work for change and freedom and liberation for Palestinian people," Silmi said.
