For Iraq, as for Vietnam, What Does It Mean to Be an American Ally?

As ISIS advances towards Baghdad, President Obama’s dilemma - just as was the case in Vietnam - is not about saving U.S. combat fatalities, but about saving a Free Iraq.

For those who are worried about whether America is going to stick with Iraq — could this be a marker for other allies? — I like to recommend paying attention to the abandonment of Free Vietnam. I’ve been thinking of it again this week as the world waits to see what, if anything, America is going to do in the face of the advance against Iraq by the forces of the Islamic State of Iraq and Syria.
