What's in a name?
A lot it seems.

About a month ago, Jabhat al-Nusra, al-Qaeda's biggest affiliate and one of the largest jihadi groups in Syria, cut it's ties with al-Qaeda and changed its name to Jabhat Fateh Al-Sham (the Front for the Conquest of the Levant).
Washington was less than impressed.

The organization claims the move is meant to foster unification among rebel factions but the US and others say it just a PR exercise...
The rebranding has been dismissed by many in the international community as little more than window dressing.
Director of National Intelligence James Clapper called it a "PR move ... to create the image of being more moderate," while State Department spokesman John Kirby said the U.S. would "judge a group by what they do, not by what they call themselves,"
Lister says the U.S.'s designation of the group as a foreign terrorist organization is unlikely to change

A PR move. Window dressing. In other words, a joke that no one in Washington, or our allies, could possibly fall for, right? You might be surprised.

Fateh al-Sham’s support extends beyond the immediate political and military opposition. Roshd Virtual University in Istanbul, Turkey offered 100 scholarships to the children of the fighters who participated in Aleppo’s battle. The opposition’s desperation to change the balance of power in Syria has made them embrace Fateh al-Sham and turn a blind eye to the fact that it was until recently the Nusra Front, an internationally designated terrorist group with ties to al-Qaeda.
According the Syria analyst Charles Lister, there is a significant subsection of the Syrian opposition that does not oppose Fateh al-Sham’s participation in Aleppo related military operations. Moreover, Lister said that opposition forces fighting in Aleppo received for the first time American weapons that are normally designated for forces fighting the Islamic State (ISIS). The opposition’s takeaway is that the United States does not object to preserving the balance on the ground with the Syrian regime, even if doing so indirectly bolsters Fateh al-Sham. Some Syrians even believe that the United States is fighting fire with fire and using Fateh al-Sham to fight the Syrian regime, Hezbollah, and Iran regulars, even at the cost of Fateh al-Sham integrating further into the opposition.

The massive battle to break the siege of Aleppo had absolutely nothing to do with ISIS. It had everything to do with the Assad government, and this rebranded al-Qaeda group was the largest participant in that offensive.

In a related note, remember when CIA-backed Syrian rebels were fighting Pentagon-backed Syria rebels a few months back? Pretty crazy, huh?
Well, guess what? They are back to doing it again, except this time Turkey is fighting alongside the CIA-backed rebels.

The operation, labeled Euphrates Shield, is also aimed at pushing back U.S.-allied Kurdish forces. The fighting pits a NATO ally against a U.S.-backed proxy that is the most effective ground force battling IS in Syria....
Turkey is part of the U.S.-led coalition fighting IS, but the airstrikes that began Saturday marked the first time it has targeted Kurdish-led forces in Syria.

Technically, Turkey is fighting alongside the Free Syria Army (i.e. CIA-backed), but in reality the Syria rebels in this offensive were drawn directly from Idlib province, which is controlled by Fateh al-Sham and its allies.

On the other side of this battle is the Pentagon-backed Syrian Democratic Forces, our most loyal and effective allies in the fight against ISIS. The SDF also happens to be who the U.S. troops are embedded with.

There was no immediate comment from U.S. officials about the escalation of fighting between the two sides—both of which receive American military support.

For the moment are soldiers aren't near the fighting, but since Turkey is border walls at Kobane, and shelling the Afrin canton, both of which are far from the battle, it appears that Turkey is preparing in case the fighting spreads.
