Clarke has said she supports a two-state solution to the Israeli-Palestinian conflict. Some of her stances have subjected her to public criticism by constituents in her district, which is roughly 20% Jewish according to estimates from a 2010 Census. In 2010, Clarke signed onto two petitions urging Obama to pressure Israel to resolve the Gaza Blockade, which she later retracted. In 2009, she voted against H.R. 867, which sought to condemn the controversial Goldstone Report commissioned by the United Nations. In 2015 Clarke indicated she would vote for President Obama's JCPOA, known as the Iran nuclear deal, despite appeals from some of her Jewish constituents and local advocacy groups to vote against the deal. In explaining her decision, Clarke said in a statement, "Iran is on the verge of creating a nuclear bomb, right now. The JCPOA provides a pathway that holds great potential to forever change this reality." In 2015, Clarke attended Prime Minister of Israel Benjamin Netanyahu's speech before a joint session of Congress after initially expressing uncertainty.
