While the representatives of Free Syria Army (FSA) are in Washington soliciting the Trump administration to restore the CIA’s ‘train and equip’ program for the Syrian militants that was shuttered in July last year, hundreds of Islamic State’s jihadists have joined the so-called ‘moderate rebels’ in Idlib in their battle against the advancing Syrian government troops backed by the Russian airstrikes to liberate the strategically important Abu Duhur airbase, according to a recent AFP report  by Maya Gebeily.
The Islamic State already had a foothold in neighboring Hama province and its infiltration in Idlib seems to be an extension of its outreach. On January 12, the Islamic State officially declared Idlib one of its ‘Islamic governorates,’ has reportedly captured five villages and claimed to had killed two dozen Syrian soldiers and taken 20 hostages.
In all likelihood, some of the Islamic State’s jihadists who have joined the battle in Idlib were part of the same contingent of militants that fled Raqqa in October last year under a deal brokered  by the US-backed Syrian Democratic Forces (SDF). In fact, one of the main objectives of the deal was to let the jihadists fight the Syrian government troops and to free up the Kurdish-led SDF in a scramble to capture oil and gas fields in Deir al-Zor and the border posts along Syria’s border with Iraq.
Islamic State’s foray into Idlib, which has firmly been under the control of Hayat Tahrir al-Sham (HTS) led by al-Nusra Front since 2015, isn’t the only instance of its kind. Remember that when the Syrian government was on the verge of winning a resounding victory against the militants holed up in east Aleppo, Islamic State came to the rescue of so-called ‘moderate rebels’ by opening up a new front in Palmyra in December 2016.
Consequently, the Syrian government had to send reinforcements from Aleppo to Palmyra in order to defend the city. Although the Syrian government troops still managed to evict the militants holed up in the eastern enclave of Aleppo and they also retook Palmyra from Islamic State in March last year, but the basic purpose of this tactical move by the Islamic State was to divert the attention and resources of the Syrian government away from Aleppo to Palmyra.
Fact of the matter is that the distinction between Islamic jihadists and so-called ‘moderate rebels’ in Syria is more illusory than real. Before it turned rogue and overran Mosul in Iraq in June 2014, Islamic State used to be an integral part of the Syrian opposition and it still enjoys close ideological and operational ties with other militant groups in Syria.
It’s worth noting that although turf wars are common not just between the Islamic State and other militant groups operating in Syria, but also among the rebel groups themselves; however, the ultimate objective of the Islamic State and the rest of Sunni militant outfits operating in Syria is the same: to overthrow the Shi’a-led and Baathist-dominated government of Bashar al-Assad.
Regarding the Syrian opposition, a small fraction of it has been comprised of defected Syrian soldiers who go by the name of Free Syria Army, but the vast majority has been comprised of Sunni Arab jihadists and armed tribesmen who have been generously funded, trained, armed and internationally legitimized by their regional and global patrons.
The Islamic State is nothing more than one of numerous Syrian militant outfits, others being: al Nusra Front, Ahrar al-Sham, al-Tawhid brigade, Jaysh al Islam etc. All the Sunni Arab militant groups that are operating in Syria are just as fanatical and brutal as the Islamic State. The only feature that differentiates the Islamic State from the rest is that it is more ideological and independent-minded.
The reason why the US has turned against the Islamic State is that all other Syrian militant outfits only have local ambitions that are limited to fighting the Syrian government, while the Islamic State has established a global network of transnational terrorists that includes hundreds of Western citizens who have become a national security risk to the Western countries.
Regarding the dominant group of Syrian militants in the Idlib Governorate, according to a recent report  by CBC Canada, Tahrir al-Sham, which was formerly known as al-Nusra Front until July 2016 and then as Fateh al-Sham until January 2017, has been removed from the terror watch-lists of the US and Canada after it merged with fighters from Zenki Brigade and hardline jihadists from Ahrar al-Sham and rebranded itself as Hayat Tahrir al-Sham (HTS) in January last year.
The US State Department is hesitant to label Tahrir al-Sham a terror group, despite the group’s links to al-Qaeda, as the US government has directly funded and armed the Zenki Brigade, one of the constituents of Tahrir al-Sham, with sophisticated weaponry including the US-made antitank TOW missiles.
The purpose behind the rebranding of al-Nusra Front first as Fateh al-Sham and then as Tahrir al-Sham, and purported severing of ties with al-Qaeda has been to legitimize itself and to make it easier for its patrons to send money and arms. The US blacklisted al-Nusra Front in December 2012 and persuaded its regional allies Saudi Arabia and Turkey to ban it, too. Although al-Nusra Front’s name has been in the list of proscribed organizations of Saudi Arabia and Turkey since 2014, but it has kept receiving money and arms from its regional patrons.
Finally, regarding the deep ideological ties between the Islamic State and al-Nusra Front, although the current al-Nusra Front has been led by Abu Mohammad al-Jolani, but he was appointed  as the emir of al-Nusra Front by Abu Bakr al Baghdadi, the leader of Islamic State, in January 2012. In fact, al-Jolani’s Nusra Front is only a splinter group of the Islamic State, which split from its parent organization in April 2013 over a leadership dispute between the two organizations.
