Former British Prime Minister Tony Blair told Congress on Thursday there is no workable alternative to a two-state solution to the conflict between Israel and the Palestinians, and both sides are in favor of it. But in practice, "they doubt it can happen," Blair told the Senate Foreign Relations Committee. "The opportunity is there," said Blair, who is the international negotiator for the Mideast on behalf of the United Nations, the United States, the European Union and Russia. "But it won't remain if not seized. As President [Barack] Obama has recognized, this is the right time to seize it." The best way to go, he said, is to try to make it clear to the Palestinians that negotiations will result in genuine statehood and to the Israelis that there can be "an agreed program for reform of the Palestinian security sector." On the Israeli side, he said, Israel will not agree to a Palestinian state unless it knows its neighbor will be secure, stable and well governed. Blair urged Obama to push quickly for negotiations, provided it clearly points to genuine Palestinian statehood. Members of the Senate panel appeared to agree there was no alternative to negotiations. "We all understand," said the committee chairman, Sen. John Kerry, D-Mass., "that peace will not come to the Middle East quickly or easily." But, Kerry said, "I share Mr. Blair's optimism that this moment presents an opportunity we cannot afford to miss."
