2 Years To Get Of Isis In Iraq

Well, it's going to take a long time to get Isis out of  Iraq.
From the Arabnews: Top officials from 21 countries kicked off talks in London on Thursday on pushing back Islamic State (IS) militants in Iraq and Syria and tackling the growing threat of homegrown militants in Europe.
British Foreign Secretary Philip Hammond said before the meeting that the task of pushing the IS militants back would be slow.
“This isn’t going to be done in three months or six months. It’s going to take a year, two years to push ISIL (IS) back out of Iraq but we are doing the things that need to be done in order to turn the tide,” Hammond told Sky News.  http://www.arabnews.com/world/news/693391
Umm, ok.  Not too many people know it's going to last that long.
And that's just Iraq.
What about the other countries?
Will Obama have the stomach to last that long?
And what kind of mess will Obama leave for the next president?
