If I understand this correctly, first and foremost Assad and Russia will get rid of both CIA trained Syrian Alliance soldiers. Once they are done with that, any other group who went against Syria, minus ISIS will be eradicated. The intention here is to send them back into Iraq.
Finally Russia and Iran, with Syrian support will start a downward movement, go village to village, town to town. city to city and destroy ISIS and anything else, (re: Sunni’s) in its path. Once the Shiites in Iraq take charge, Iran will become firmly entrenched in Iraq.
Kuwait and Saudi Arabia will then have the Shiites on their doorstep.
And all because the President of the United States thought it was a good idea to kill Qaddafi, let the Bruthas take over Egypt, let Yemen fall apart, let Islam kill thousands of Christains all over Africa and the Middle East and finally try to dislodge Assad from his post.
Obama might actually be the 12th Mahdi.
