The Progressive List for Peace (Hebrew: הרשימה המתקדמת לשלום, HaReshima HaMitkademet LeShalom, Arabic: القائمة التقدمية للسلام) was a left-wing political party in Israel.

He was charged with having written graffiti on 117 tanks and other military vehicles, exhorting soldiers to refuse service in the Occupied Territories, and with having taken down the standing orders from a military billboard and replaced them with PLP leaflets expressing "anger and protest" at "the systematic killing of Palestinian unarmed demonstrators" and calling for "the creation of an independent Palestinian state, side-by-side with Israel".

Both under interrogation and at his trial, Keller repeatedly reiterated that he had acted completely alone, without any involvement by other members of the party or of the party as such, that the PLP leaflets were left over in his bag from a meeting which he attended on the night before his call-up order, and that he had not brought them to the army with any premeditated intention of exposing soldiers to them but rather had placed them on the military billboard as a sudden reaction to radio news of especially harsh acts of oppression by soldiers on the West Bank.

However, Keller's wife Beate Zilversmidt was received with a standing ovation at the PLP's conference, held in Nazareth during the second month of his incarceration, and the party members—even though not consulted in advance—clearly approved of his act.

In a meeting held in Tel Aviv on April 22, 1994, to mark ten years since the formation of the PLP, the party's former spokesperson Adam Keller stated: When we formed the Progressive List for Peace, we hoped to create a political force composed of Jews and Arabs together, which would become a permanent feature of the Israeli political scene.

But we did achieve something quite important: to make Israel more of a democracy, by letting its Arab citizens have more of a real exercise of the ballot box...

Any group of Arabs which tried to set up a party which was neither government-subservient nor Communist got immediately banned, like Al Ard... Now, though the PLP is gone, its legacy remains.
