There's a reason for that

Hillary Clinton accused a questioner in New Hampton, Iowa, of being "put up" to asking why he should back her when she had just demonstrated that she'd failed to learn her lesson on trusting the administration; after buying the story and voting "for" on the Iraq war, now she's trusting them on Iran and voting on a Sense of the Senate resolution to label the Revolutionary Guard "a terrorist organization" - playing right into the Cheney camp. He took offense at the accusation, and she apologized and said that she had been asked “the very same question in three other places.”

Well, sure she has. People who have been paying attention to her are going to want to know how she's different from the aggressive, militant, war-mongering (in the literal as well as figurative sense of the word) current occupant of the White House and his cronies. One of the reasons we want them out is the damned war they've gotten us into and the ones they apparently want to get us into.

Get used to hearing the question, Hillary. And try to come up with a better answer - one that doesn't show you want to be seen as tough, regardless of the consequences.
