The US invasion and occupation to find the WMD that were supposedly hidden from UN inspectors in March 2003 was over in 2008 when Bush announced the Iraqis were ready to defend themselves and no WMD were ever found. So that means that zero US troops should have been left in Iraq after the deadline that Bush and Maliki agreed to came to pass. What is going on now is a new war against the IS terrorists.
And No US troops will be needed for direct combat in Iraq so your question is as wrong and stupid as the statement you made a couple months ago.

Give it up. You've been exposed. You have no idea what you are talking about in the past. So you have nothing worthwhile to say about the future.
Air strikes and advisers will suffice in Iraq.
