Here is the breakdown for Biden's claim:
CRS Report for Congress
The Cost of Iraq, Afghanistan, and Other Global War on Terror Operations Since 9/11
(found on fas.org site)
Covers FY2001 - FY2009
Afghanistan war $172 billion (8 yrs)
Iraq war $653 billion (6 years)
Let's just take average / year / week
AF: $21.5 billion / yr
IR: $109 billion / yr
7 years of AF $150.5 billion
3 weeks of IR $6.3 billion
Did it spend as much in three weeks in Iraq as seven years in Afghanistan?
