Memo to Lieberman

Joe Klein reports that Joseph Lieberman is working hard to make the Hamas "endorsement" of Barack Obama a campaign issue. I would point the senator to Obama's interesting, and credible, answer to me on the question of why Hamas's Ahmed Yousef would say what he said. Please take careful note of the last sentence:

"It’s conceivable that there are those in the Arab world who say to themselves, 'This is a guy who spent some time in the Muslim world, has a middle name of Hussein, and appears more worldly and has called for talks with people, and so he’s not going to be engaging in the same sort of cowboy diplomacy as George Bush,' and that’s something they’re hopeful about. I think that’s a perfectly legitimate perception as long as they’re not confused about my unyielding support for Israel’s security."

Which part of "unyielding support for Israel's security" is unclear?
