The Iraq War: How We Spent $800 Billion (and Counting) Follow @sarah_childressMarch 18, 2013, 1:36 pm ET. The Iraq war cost twice as much as the war in Afghanistan, and more than 16 times as much as the Bush administration predicted.
emitter. 1  a person or thing that emits. 2  Electronics. an electrode on a transistor from which a flow of electrons or holes enters the region between the electrodes.
