Army leaders were hit Tuesday with what Sen. Dick Durbin, D-Ill., called a “town hall” question about how Russia could be a top threat to the U.S. with a relatively tiny defense budget.

Moscow spends about $80 billion per year on defense, about 11 percent of the U.S. defense budget, which is set to top out at $717 billion in the coming year, Durbin pointed out during a Senate Appropriations Committee hearing on the Army’s annual spending.
