These are the words of former Palestinian national-team player Mahmoud Sarsak, whose imprisonment by Israel in 2009 and subsequent hunger strike in 2012 launched an international solidarity campaign, which eventually secured his freedom. Now Sarsak is lending his voice, along with 130 Palestinian sports clubs, to an open letter to Adidas, urging the brand to cease its sponsorship of the Israel Football Association over the IFA’s acceptance of teams that form in illegal Israeli settlements in the Palestinian territories. This call takes on a new urgency in the wake of last week’s mass shooting, according to The Guardian, of 773 Palestinians during protests by the Israeli Defense Forces. Fifteen people were killed.

The Israel Football Association not only includes teams that exist in illegal settlements in their soccer federation; it also encourages the creation of even more teams, despite the condemnation of these actions by the United Nations. This amounts to the use of the “beautiful game” as a tool of ethnic cleansing and displacement in communities throughout areas that in theory could form the basis of a Palestinian state. The IFA is able to perpetrate these actions in part because it is backed financially by Adidas, a global corporation, with a brand value—according to Forbes—of $6.8 billion.

In an open letter to Adidas CEO Kasper Rørsted, these 130 Palestinian sports clubs accused Adidas of whitewashing—let’s just call it “sportswashing”—human-rights abuses and openly flouting UN Security Council Resolution 2334, which “denounces Israeli settlements as flagrant violations of international law.” The letter threatens an international boycott campaign against Adidas if it doesn’t take immediate action to cease its support of the Israel Football Association, for as long as the IFA continues to organize teams among the settlements. Signatories to the letter include the storied Jenin Athletic Club, which, founded in 1940, is the oldest Palestinian sports organization in the West Bank, predating the founding of the state of Israel by eight years. (We asked Adidas for comment and as of the time of publishing, have not received a response. If they do have a statement, we will add their response to this piece.)

The question that also hangs over the letter is whether a boycott campaign could provoke some of Adidas’s athletes to say or do something about the settlements. International soccer has long been a place where players have spoken out for Palestinian rights, and Adidas is also the sponsor of dozens of some of the most famous soccer players on earth, including Uruguay’s Luis Suarez and the Argentinian great Lionel Messi.

An international campaign could also ricochet into US sports as well. NFL players who are human billboards for Adidas include Green Bay Packers quarterback Aaron Rodgers and Dallas Cowboys QB Dak Prescott. NBA players who are sponsored by Adidas include James Harden and Derrick Rose. Rose in particular has been outspoken in his support of the Black Lives Matter movement, being the first player to wear an “I Can’t Breathe” shirt after the police killing of Eric Garner in 2014. One wonders if Rose will become another athlete to see the connections between the Black Lives Matter struggle and the suppression of Palestinian rights, as activists across the world continue to make connections and find commonalities between their two struggles.

However this ends, Adidas and the Israel Football Association have been put on notice: Sports will not be used as a tool of displacement or ethnic cleansing without confrontation and conflict. This story won’t remain on the athletic field, and the more attention it receives, the more Adidas will feel compelled to respond.
