Democratic White House hopeful Barack Obama Tuesday slammed President George W. Bush for pouring US firepower into Iraq, saying any new terror strike on US soil would likely derive from Afghanistan. The speech, to be delivered later Tuesday in Washington, is designed to set the stage for Obama's looming trip to Iraq, Afghanistan, the Middle East and Europe. Following are some main excerpts, released by his campaign: "If another attack on our homeland comes, it will likely come from the same region where 9/11 was planned. And yet today, we have five times more troops in Iraq than Afghanistan." Obama promised to concentrate on five main goals: "ending the war in Iraq responsibly; finishing the fight against Al-Qaeda and the Taliban; securing all nuclear weapons and materials from terrorists and rogue states; achieving true energy security; and rebuilding our alliances to meet the challenges of the 21st century."
