Bush accused of twisting history with Vietnam comparison
"My understanding of the history of the Vietnam war and the lessons of that differs rather dramatically from Mr Bush's," Robert Hathaway, an Asian expert at the Washington-based Woodrow Wilson Center for Scholars, told AFP.
Retired US Brigadier General John Johns, an expert on counter-insurgency who served in Vietnam, said Bush was "cherry-picking" history to support his case for staying the course in Iraq.
"What I learned in Vietnam is that US forces could not conduct a counterinsurgency operation. The longer we stay there, the worse it's going to get," he said.
Steven Simon of the Washington-based Council on Foreign Relations, echoed the comments.
Bush "emphasized the violence in the wake of American withdrawal from Vietnam. But this happened because the United States left too late, not too early," he said.
