Answer by taking a quote from the following article:

Thomas Dale "Tom" DeLay (; born April 8, 1947) is a former member of the United States House of Representatives, representing Texas's 22nd congressional district from 1985 until 2006. He was Republican Party (GOP) House Majority Leader from 2003-05. DeLay began his career as a politician in 1978 when he was elected to the Texas House of Representatives.

DeLay has been a strong supporter of the State of Israel, saying, "The Republican leadership, especially that leadership in the House, has made pro-Israel policy a fundamental component of our foreign policy agenda and it drives the Democrat [sic] leadership crazy--because they just can't figure out why we do it!" In a 2002 speech, DeLay promised to "use every tool at my disposal to ensure that the Republican Conference, and the House of Representatives, continues to preserve and strengthen America's alliance with the State of Israel." On a 2003 trip to Israel, DeLay toured the nation and addressed members of the Knesset. His opposition to land concessions is so strong that Aryeh Eldad, the deputy of Israel's conservative National Union party, remarked, "As I shook his hand, I told Tom DeLay that until I heard him speak, I thought I was farthest to the right in the Knesset." Former Mossad chief Danny Yatom said "The Likud is nothing compared to this guy." In 2005, in a snub to the Bush administration, DeLay was the "driving force behind the rejection of direct aid" to the Palestinian Authority. The deal had been brokered by the American Israel Public Affairs Committee. In the wake of the legislation, some Jewish leaders expressed concern "about the degree to which the Texas Republican, an evangelical Christian who opposes the creation of a Palestinian state, will go to undercut American and Israeli attempts to achieve a two-state solution." DeLay has long been a strong critic of Cuban leader Fidel Castro's regime, which DeLay has called a "thugocracy", and a supporter of the U.S. trade embargo against Cuba.

What was a major foreign policy bill he introduced?
