American ‘jihad’ fueled by 'risky source' inside US borders, warns national security expert

A national security expert warns of a 'risky source' contributing to terrorist activity inside the US after an Iraqi militia leader was charged with directing terror attacks. The expert cites vetting failures and a generous social welfare system as factors that leave the US vulnerable to terrorism. The charges against Mohammad Baqer Saad Dawood al-Saadi include orchestrating nearly 20 terrorist attacks across Europe.
