Israeli government saw a possible means to close down the money channel through United States courts. It pressed Daniel's parents to file suit, saying it would provide evidence, including a witness named Uzi Shaya who had gone to China dozens of times in his role as an Israeli counterterrorism official, and other support. In the words of Lee Wolosky, a Wultz family lawyer, this was an Israeli operation "to use our courts to achieve a sovereign objective." Because that objective seemed critically important, the Wultzes wanted to cooperate." The Israeli policy change came about at the same time Israeli Prime Minister Benjamin Netanyahu traveled to Beijing for an official state visit to China. Israeli and American media reported Prime Minister Netanyahu agreed to prevent Israeli officials from continuing to support the American legal action against Bank of China in return for the state visit and potential for increased economic, political and trade cooperation between Israel and China. While the government of Israel had previously allowed former Mossad agent Uzi Shaya and others with direct knowledge of contacts between Israel and Bank of China to provide evidence and testimony regarding meetings with Bank of China officials, following Netanyahu's reported agreement with Chinese officials, the government of Israel claimed allowing Mr. Shaya to provide the same information through direct testimony in a U.S. Court would jeopardize Israeli national security interests. In a ruling on the issue, U.S. District Judge Shira Scheindlin agreed to quash a subpoena against the former Israeli intelligence officer, writing: "no evidence suggests that Israel intended to waive Shaya's immunity" regarding information he learned in his official capacity as a Mossad agent. Israeli media called the court's decision a "shocking blow" for the Wultz family's case against Bank of China, reporting, "A US federal court has delivered a major and shocking blow to the case of terror victims' families against the Bank of China, granting Israel's request to block a key former government agent from testifying on behalf of the families' case." Conflict between U.S. and Israel Leading American lawmakers, such as Ileana Ros-Lehtinen, considered a key longtime supporter of the U.S.-Israel relationship and chair of the House Foreign Affairs Committee that oversees U.S. aid and cooperation with Israel, expressed outrage at Netanyahu's decision to prevent Shaya from testifying in U.S. court, despite his acceptance of a subpoena, and what they considered Israeli efforts to undermine U.S. judicial proceedings.
