WASHINGTON (Reuters) - Democrat Hillary Clinton charged on Monday the Iraq war may end up costing Americans $1 trillion and further strain the economy, as she made her case for a prompt U.S. troop pullout from a war “we cannot win.”

This week marks the fifth anniversary of the U.S. invasion of Iraq, but voters now say the economy is their top issue in the campaign for the November presidential election.

Clinton, the former first lady who is trying to convince voters she has foreign policy gravitas, hurled criticism both at her rival for the Democratic presidential nomination, Illinois Sen. Barack Obama, and the Republicans’ choice, Arizona Sen. John McCain.
