President Barack Obama’s decision to join Western intervention in Libya is raising concerns in the United States about the cost and duration of the military operation.

A protracted conflict in Libya adds to the Defense Department’s budget worries.

“Just the missiles cost $1 million each. So that’s, what, $112 million in the first hour?” said Larry Sabato, a political science professor at the University of Virginia.

“We have just spent months debating how many billions we’re going to cut from various domestic programs. That is the focus in Washington. It does seem incongruous to a certain degree,” he said.
