That explains how YPG took so much land.
THe mayor question should be why ISIS does not attack the Kurds and try to take zones
from them in northen Syria. If you look at the map of ISIS positions ,you will see them quite happy to having Kurds in their rear flank for mysterious reasons. A quick look at Russia
released map of from where ISIS multimillionaire Oil business , transport its oil , will show
they use Kurds zones to transport oil trucks. In other words ,there is a major agreement
between Kurds in SYria and IRAQ and ISIS to allow them transfer oil trucks through their territories and a deal like this could only happen with the heavy support of US,UK and France
and Saudi Arabia. So for me is clear , that ISIS is not interested to capture kurdish zones ,
they want instead Syrian government ones. At times kurds fights ISIS and vice versa but it doesnt happens frecuently. So this shows why the so called Kurds ,"The Most effective force" against ISIS" according to many ignorants.. happens only because in reality they are not focused
in fighting each other ,Kurds remain neutral ,neither pro ISIS ,neither pro Asad and they try to avoid each other . So this is the reason why a force like Kurds ,that do not have tanks ,do not have satellite logistics ,do not have much artillery can be so effective in the media.
IF US,NATO and Saudi Arabia who backups ISIS ,were at war against Kurds ,long time ago withing 2012 , they will have over run all Kurds positions in Syria and IRAQ. But if you look at
terrorist from all factions and kurds ,their territory advances , you will clearly see , that Kurds have been the faction who more have benefit from this war , since they never lost major territory in the entire 6 years of war. incredible but true. All they have achieved is taking more territory from Syria , in the name of "fighting ISIS".
And this is the real game here. First NATO and Saudi Arabia unleash a hundred of thousand jihadist to fight Syria and IRAQ.. they gain territory , later NATO pretends to be fighting ISIS and annex the territories they "liberate" for the kurds. So that way they can justify the transfer of land. So in reality what happens is , First Terrorist take territory away of Syrian and IRAQ army. Second NATO takes back the territories of the terrorist and give it to Kurds ,next Kurds claim their independence over their new territories given for free by NATO , and this allow later the west to legalize their illegal partition of Syria. So Kurds are not any better fighting than the Syrian local conscripts who helps the Syrian army. What makes kurds so effective is that they are in reality not the main focus of any terrorist group. The territories and kurds positions in Syria tells it all . They are indirect allies ,not because they like each other but because their mutual allies ---> NATO does not allow their terrorist assets to fight the kurds. Since the kurds is the card NATO needs to justify partition of Syria. after the FSA disbanded.
Truly most people are not aware of the big deceptive games being played in Syria.
Kurds are not religious extremist ,but they are opportunistic ,and seeking to take advantage
whenever they can to partition Syria and get their most hoped Independence.
