O’Connell, a law professor at the University of Notre Dame, is a determined and eloquent critic of drone strikes. She believes that while strikes in well-defined battle spaces like Iraq and Afghanistan are justified, and can limit civilian deaths, strikes in Pakistan, Yemen, Somalia, and other places amount to “extrajudicial killing,” no matter who the targets are. Such killings are outside the boundary of armed conflict, she says, and hence violate international law. Mary Ellen O’Connell Short Professor of Law
