If Saddam was still in power, there would be no ISIS.
Saddam summarily executed all trouble makers, especially the Jihadists.
Nonsense. Saddam hosted a World Trade Center bomber, gave him a house and a pension; he also funded the families of suicide bombers, and he armed and funded the Philippine Islamic group that was beheading tourists in the 90s. He also provided counterfeiting training to al Qaeda.
Baathist Iraq even hosted the Ayatollah Khomeini- a Shiite, whose supporters were seen by the Baathists as a useful foil against the Shah of Iran, before Khomeini moved to France. Saddam was not the leader then but he was part of the Baath party security apparatus.
