From the floor of the New York Stock Exchange Jim Cramer tells investors what they should watch out for in the week ahead in Iraq and how it will affect oil prices back here in the United States. Cramer tells TheStreet's Joe Deaux that waiting on the sidelines may be the safe choice as the possibility of all-out conflict leaves much uncertainty as to how volatile price swings may become. Islamist militant group ISIS has taken control of large swaths of north Iraq, which holds some one-third of oil produced in the country. The group also controls some areas in Syria and could be poised to gain more ground in Iraq.
