Following a shooting rampage by a United States Army sergeant who allegedly killed at least 16 civilians in southern Afghanistan, Newt Gingrich and Rick Santorum are saying that the United States should reassess its role in the country. "I think that weâre risking the lives of young men and women in a mission that may frankly not be doable," said Gingrich on "Fox News Sunday." "I think it's very likely that we have lost, tragically lost, the lives and suffered injuries to a considerable number of young Americans on a mission that weâre going to discover is not doable." Santorum said the recent news was a call to at least reassess the situation.
