Sen. Hillary Clinton (D-NY) suspended her candidacy for the Democratic nomination June 7 . Clinton, who had advanced farther than any woman presidential candidate in U.S. history, sought throughout the campaign season to distinguish her foreign policy agenda from that of her main opponent, Sen. Barack Obama (D-IL).

In a concession speech Saturday, Clinton endorsed Obama and urged her supporters to work for his election.

Here is a review of Clinton’s key foreign policy positions:

• Clinton said she would end the war in Iraq. Although she voted in favor of the 2002 Senate resolution authorizing the use of force in Iraq, she has since become critical of the war, opposing the troop surge and the use of private military contractors there. Clinton’s plan to end the war included a phased redeployment of troops beginning within the first 60 days of her administration. She also said she would keep “small, elite strike forces” in Iraq “to engage in targeted operations against al-Qaeda.”

• Clinton said she would open a diplomatic channel with Iran upon taking office, but also warned the country about its aggression toward Israel, saying in April 2008 that the United States would “totally obliterate” Iran if it were to “foolishly consider launching an attack on Israel” under her presidency. Clinton also received criticism from her Democratic opponents for her September 2007 vote in favor of the Kyl-Lieberman amendment, which labeled the Iranian Revolutionary Guard a terrorist organization.

• Clinton promised to renegotiate NAFTA to improve the trade deal’s labor and environmental protections. She planned to implement a “time out” on new trade deals during her first months as president so she could “assess their impact before going forward.” Clinton also said she would crack down on China’s “unfair trade practices,” including the revaluation of the yuan.

• Clinton said she would maintain the U.S. embargo on Cuba and would pressure the Cuban government to release political prisoners and become more democratic.

• Clinton planned to institute a cap-and-trade program for carbon emissions and create a $50 billion “Strategic Energy Fund,” funded in part by oil companies, to invest in alternative energy. She also said she would create a “green collar” jobs program.

• Clinton said she would visit Africa during her first term, if elected. She called for a no-fly zone over Darfur, Sudan, but said she would not send U.S. troops to stop the mass killings there. Clinton signed a statement in May 2008 saying the Khartoum regime was “chiefly responsible” for the violence in Darfur and demanding that it adhere to the standards of the Comprehensive Peace Agreement.
