Yet that is where logic leads. Clinton, like Johnson, started bombing without thinking much about what to do next. Clinton evidently thinks the same thing. But bombing is an act of war and changes the situation irrevocably. There is not even a counterargument in Kosovo, as there was in Vietnam, that ground action risked a counterattack by a superpower.
Liberals tend to prefer soggy over crunchy policies.
As defined by the Economist in 1988, soggy choices leave things ambiguous and options wide open while crunchy choices leave clear and unambiguous results. Johnson and Clinton saw bombing as a soggy choice, but other liberals were wiser. Fighting a ground war in the former Yugoslavia will not be easy, and asserting proconsular authority over Serbia will be even harder.
