Only half of Iraq’s security forces are capable of actually fighting back against the insurgence of militants in the country, according to a secret American report. The findings describe units that have been heavily infiltrated either by informants of the invading Sunni militias or Shiite groups that were trained in Iran and had previously fought against American troops in Iraq. This could pose great danger to hundreds of American advisers sent to Iraq, although not supplying assistance could be even more risky in the long run, according to the report. The report will be sent to Defense Secretary Chuck Hagel this week.
