ISIS Abandon Capital City Of "Raqqa", US Playing Dirty

Things are coming to a head in Syria. The ISIS have been chased out of their 'self declared' capital of Raqqa in Syria. 

Who will fill the vacuum? The US wants to help the Kurds create an independent Kurdish state in Syria.

The Syrian government with Russian assistance wants to reimpose Syrian rule over all its territories. 

My view is after the ISIS are kicked out, new fighting will erupt between the different groups who want to control Syria. Here is some news :

1.  ISIS Leave Raqqa, Cross Euphrates 

ISIS militants cross Euphrates in Syria from stronghold of Raqqa 

despite being encircled by Kurdish and US-led coalition forces

SDF, US, UK, French special forces "blocked" Raqqa from north
SDF stopped offensive, ruptures in encirclement

ISIS cross Euphrates to southern direction of Syria

Russian do utmost to prevent ISIS breaking through from Raqqa

first ISIS convoy from Raqqa to Palmyra destroyed by Russian Air Force May 25

IS made another attempt on May 29 to 30

3 motorcades left Raqqa under darkness
destroyed 80 jihadists, 36 vehicles, eight fuel trucks and 17 pickup trucks 

There are serious accusations that the US is "slowing" down the eviction of ISIS until their allies are in position to take territory vacated by ISIS :

2.  Double Game: ‘US Secretly Supports ISIS in Raqqa’ 

US actively supports SDF in Raqqa but secretly endorses ISIS

cooperation between these forces under US control

US has destroyed all bridges across Euphrates
intention to liberate Raqqa 

next stage before establishing Kurdish state

Kurdish state will border oil fields of Syria

SDF are main allies of US and ISIS 
ISIS are American soldiers in local clothes

US is coordinating between ISIS and SDF

agreements concluded under strict guidance of US 

when US tell ISIS to leave they leave unconditionally 

vacating a spot for another American ally

US can destroy ISIS within 24 hours

US weapons transfers to Kurdish (YPG) to consternation of NATO ally Turkey

Kurdish fighters recipients of US arms and vehicles to take Raqqa 

Conclusion : The ISIS terrorists will be heading for home, to create more killing and chaos in their home countries.   The fighting in Syria will continue. Nothing much will have been achieved.
