So why are some of the Allied forces against Isis Trying to stop any progress?

The summit that was being held with the allies fighting against Isis, was suspended until March, as of last Friday evening. The reason given for this postponement was because of infighting amongst the allied group of countries against Isis forces.
Questions of Russian and Syrian actions, the Middle Eaststern coalition, headed by Saudi Arabia and it’s members, have been accused of delayed participation in their supporting efforts, Russia is accusing Turkey of aggressive build up towards attack in recent activity between the two nations, and so on.
Wasn’t one of the initial ideas towards the destruction of Isis was from creating conflict from within their infrastructure? It could be argued that this tactic is destroying the Allied forces from within, sooner than these efforts against Isis will occur.
The Associated Press gave an inclusive report of all Allied participants detrimental actions, which has now delayed any action towards the halting of ISIS forces. Another city has fallen to their troops since.
What is the eventual outcome going to be?
Is this multi-nation group going to be effective now and in the long-run?
