Ehud Barak stomps down the aisle of the old, white Boeing 707 that doubles as Israel's Air Force One. He has come to shmooze with the traveling press corps. Close up, he is shorter than expected. He clenches his shoulders like a muscle-bound wrestler. His pudgy face looks as if it was molded from children's modeling dough, his hair as if he still has it trimmed by his old army barber. No $200 stylist at the airport for him.
