Also, the US held off getting involved again for quite a while, in line with the White House's position that it didn't want to bail Maliki out of his mess by fixing his problems for him. It only did get involved when Isis looked to be gaining too much momentum, and then put massive pressure on Maliki to actually step down. I really don't think there's been a huge appetite to re-engage in Iraq.
