And yet this is precisely what President Barack Obama has done by attacking both the Islamic State and Jabhat al Nusra in Syria. While both groups have very similar al Qaeda outlooks, they have played very different roles in the struggle in Syria. ISIS has an Iraqi leadership and has built its ranks largely by recruiting foreign jihadists. It also has avoided combat with the Assad regime just as the regime has forgone attacks against ISIS, even while the terrorist group claimed growing expanses of Syria for itself.
Al Nusra Front has Syrian leadership and mainly Syrian fighters. It also has a pretty decent record of working with the more democratic forces in the Syrian rebellion and it has actually been fighting the Assad regime. Most importantly with regards to the current campaign against ISIS, al Nusra has been one of the main forces fighting ISIS in Syria.
When the Obama administration announced that it had attacked the "little known" Khorasan group as well as ISIS in Syria, it was really talking about al Nusra, or a section of it. The reason those of us that have been following events in Syria for years never heard of this "Khorasan group" before now is that the name was entirely the creation of the "Obama group", just as the term "Viet Cong" was never what the National Liberation Front fighters in Vietnam called themselves. It was the creation of a US army psyops officer in 1958 which was immediately picked up by all the media. The new name "Khorasan group" is a thin veil to cover what they are really doing just as their story about an "imminent attack" on the US by these fighters around Idlib and Aleppo is a thin story to cover Obama's attack on ISIS's opposition in Syria.
The Pentagon was so proud to show how precisely they could use smart bombs to take out an antenna array on top of an ISIS command and control building without harming the building itself - or the expensive radio equipment and ISIS commanders inside. Such a strategic attack would have made sense, knocking out ISIS communications, if it was part of an immediate ground assault, otherwise it means very little because antenna arrays can quickly be replaced, and at very little cost.
The Obama administration was also so kind as to give the Assad regime a "heads-up" as to the coming attack. ISIS also had plenty of time to fortify and reposition itself in preparation for the US air campaign. In fact the only forces caught by surprise were those that have been fighting both the Assad regime and ISIS.
