CMV: The USA's renewed military action in Iraq shows they are protecting their oil interests in the region as no action has been taken in similar circumstances in Syria

I know this topic has been covered in the past with regards to Iraq. However, in recent weeks, in the context of ISIS forces in both countries, it begs the question why the US has deployed troops in Iraq when the same forces also occupy Syria and are committing similar war crimes. The most obvious difference being the need to establish a stable government in Iraq to ensure oil production, though are there other reasons. Would the US really wage a war based on morality in Iraq, given the lack of action seen in Syria and Palestine that both have well documented cases of war crimes?

Most oil contracts in Iraq are not held by US companies, but Chinese ones.  Most Iraqi oil is not sold to the US.  The "US fought for oil in Iraq" narrative only works in the sense that the world market is hurt by the disruption of Iraqi oil.

2nd Edit - And if that seems like a selfish thing for the world to do, consider what resource ultimately supports many of the population centers in the Middle East and how well they would fare without a flow of oil revenue.

The more likely explanation is that the US is heavily *politically* invested in the success of the Iraqi government and wants to contain the situation in Syria.  We have a clear ally to support and relatively clear battle lines and objectives.  Those aren't present in Syria and not applicable to Israel/Palestine.

Intervening heavily in Syria is essentially a commitment to adjudicate one of the most complicated civil wars in recent history, so it's understandably been avoided.  Intervening in Israel/Palestine is complicated by preexisting US relations with Israel and the fact that we really aren't politically able to do much more than lightly chastise Israel.

Edit-Also, the US is not reinvading Iraq.  They've sent security personnel to augment US bases and likely have special operations folks embedded with the ISF to coordinate air support.
