Sorry David, but that AP article is a precise repeat of the same nonsensical mistake all the Western media is doing: namely, that of pouring more water to the Daesh's mills.

See this:
In neighboring Syria, days of airstrikes have been unable to stop militants on the verge of capturing a strategic town on the Turkish border.
This is making the Daesh appear in the public as if it cannot be even hit by air strikes. Actually, the situation is such that air strikes are 'too little, too late', and run in disjoined fashion.

To explain what I mean, have a look at the summary of CENTCOM's (and few DOD's) releases for activity over Syria since 23 September:

CENTCOM, 23 September:
U.S. military forces and partner nations, including the Kingdom of Bahrain, the Hashemite Kingdom of Jordan, the Kingdom of Saudi Arabia, Qatar and the United Arab Emirates, undertook military action against ISIL terrorists in Syria overnight, using a mix of fighter, bomber, remotely piloted aircraft and Tomahawk Land Attack Missiles to conduct 14 strikes against ISIL targets.

The strikes destroyed or damaged multiple ISIL targets in the vicinity of Ar Raqqah, Dayr az Zawr, Al Hasakah, and Abu Kamal and included ISIL fighters, training compounds, headquarters and command and control facilities, storage facilities, a finance center, supply trucks and armed vehicles.
...
CENTCOM, 23 September:
U.S. military forces continued to attack ISIL terrorists in Iraq and Syria, using a mix of bomber and remotely piloted aircraft to conduct three airstrikes last night and today.

Two of the airstrikes were conducted last night as part of the operation over Syria and resulted in one damaged ISIL armed vehicle and one destroyed ISIL armed vehicle southwest of Dayr Az Zawr.
...
To date, U.S. Central Command has conducted 194 airstrikes across Iraq against ISIL. Along with partner nations, U.S. Central Command has also conducted 16 airstrikes across Syria against ISIL.
CENTCOM, 24 September:
A fifth airstrike damaged eight ISIL vehicles in Syria northwest of Al Qa'im. All aircraft exited the strike areas safely.

CENTCOM, 24 September:
U.S. military forces and partner nations, including the Kingdom of Saudi Arabia and the United Arab Emirates, attacked ISIL terrorists in Syria today, using a mix of fighter and remotely piloted aircraft to conduct 13 airstrikes against 12 ISIL-controlled modular oil refineries located in remote areas of eastern Syria in the vicinity of Al Mayadin, Al Hasakah, and Abu Kamal and one ISIL vehicle near Dayr az Zawr, also in eastern Syria.
...
To conduct these strikes, the U.S. employed U.S. Air Force fighter aircraft deployed to the U.S. Central Command area of operations. In addition, the Kingdom of Saudi Arabia and the United Arab Emirates also participated in these airstrikes. All aircraft safely exited the strikes areas.
For 25 September 2014, there are no CENTCOM-reports related to air strikes against targets in Syria.

CENTCOM, 26 September:
In Syria, three airstrikes south and southeast of Dayr Az Zawr destroyed four ISIL tanks and damaged another.
CENTCOM, 27 September:
In Syria, an ISIL vehicle was destroyed south of Al-Hasakah. Also near Al-Hasakah several buildings that were part of an ISIL garrison were destroyed. An ISIL command and control facility near Manbij was damaged. An ISIL building and two armed vehicles at the Kobani border crossing were destroyed. An ISIL held airfield, an ISIL garrison and an ISIL training camp near Ar Raqqah were damaged.

To conduct these strikes, the U.S. employed U.S. Air Force and U.S. Navy attack and fighter aircraft deployed to the U.S. Central Command area of operations. In addition, the Kingdom of Saudi Arabia, the Hashemite Kingdom of Jordan, and the United Arab Emirates also participated in these strikes. All aircraft exited the strike areas safely.
CENTCOM, 28 September:
In Syria, two airstrikes near Dayr ar Zawr destroyed one ISIL tank and damaged another. One airstrike in northeast Syria destroyed three ISIL armed vehicles and an ISIL Humvee. U.S. and partner nations conducted airstrikes on four ISIL-held modular refineries and an ISIL command and control node north of Ar Raqqah; although we continue to assess the outcome of these attacks, initial indications are that they were successful.

To conduct these strikes, the U.S. employed U.S. Air Force and U.S. Navy fighter aircraft deployed to the U.S. Central Command area of responsibility. In addition, the Kingdom of Saudi Arabia and the United Arab Emirates also participated in these strikes. All aircraft departed the strike areas safely.
CENTCOM, 29 September:

Two airstrikes were conducted on ISIL compounds near Ar Raqqah, while two other airstrikes struck an ISIL training camp and ISIL vehicles within a vehicle staging area adjacent to an ISIL-held grain storage facility near Manbij. The storage facility was being used by ISIL as a logistics hub and vehicle staging facility. Although we continue to assess the outcome of these attacks, initial indications are that they were successful.

To conduct these strikes, the U.S. employed U.S. Air Force aircraft deployed to the U.S. Central Command area of responsibility. In addition, the United Arab Emirates and the Kingdom of Jordan also participated in these strikes. All aircraft departed the strike areas safely.
