In the constant argument that is Middle East politics it is very rare to achieve anything like universal agreement, but no one can begrudge what Hazem Chehabi did. He quit. Since Chehabi resigned last week as honorary consul general of Syria in Southern California, he has received hundreds of e-mails and phone calls. All positive. For 18 years, Chehabi, an oncological radiologist in Newport Beach, has volunteered to act as Syria’s consul general here. His office handled travel documents and birth, marriage and death certificates for the thousands of expatriate Syrians living in the Western states.
