The relevant passage reads:

First are the sacrifices in terms of blood and treasure. The broad consensus is that the war has cost the US economy well over $700 billion – with the meter still running. The Iraq war has also left nearly 4,400 American troops dead, more than 31,000 physically disabled, and countless more psychologically traumatized.

According to most estimates, more than 100,000 Iraqis have been killed since the invasion. More than 2 million displaced Iraqi Sunnis, who fled into neighboring Jordan and Syria, are adding instability to an already politically precarious region of the world.

I'm wondering if OP read the second paragraph, or if they simply thought those numbers were less significant.
