Sunday, 2 a.m. local RAMADI My flight to Ramadi left from a heliport in Baghdad's so-called "Green Zone." For Americans, this is probably the safest place in the country. It is a grid of protected streets along the banks of the Tigris River, surrounded by high concrete blast walls and coils of barbed wire, where suicide bomber-weary tank turrets point at passing traffic. There is high security here because this is home to the U.S. Embassy as well as the seat of the Iraqi government. Most everything outside, they call the "Red Zone." {{{ SNIP }}}
