“There is no question that the offensive against Mosul is partly designed to achieve a strategic redeployment of ISIS forces from Mosul in Iraq and into Syria to reinforce Raqqah,” Jatras said on Friday night in his speech to Iranian state-owned television channel Press TV.
He said the US policy is based on using terrorist groups as a geopolitical tool, saying successive American administrations have done that.
“We did it in Libya, we did it in Bosnia, we did it in Kosovo, we did it in Afghanistan against the Soviet Union, we have a very long history of using these very radical groups as geopolitical tools against people we don’t like.”
Jatras said the US had spent millions of dollars to train the so-called moderate militants in Syria but in fact most of them had joined al-Qaeda or Daesh terrorist groups.
The expert roundly rejected the claim that there are some moderate militants in Syria.
“People who for ideological or religious goals want to attack innocent people and kill them in order to impose some kind of an ideology on them, I think that constitutes terrorism," he said.
"And I think trying to overthrow a government of another country to achieve that purpose is terrorism,” Jatras added.
For his part, Jihad Mouracadeh, a political analyst from Beirut, ruled out the accusation that the US and its allies want to redeploy ISIS from Mosul into Raqqah.
He said the US and NATO are planning to attack the Syrian city; "so, it seems to be illogical to redeploy ISIS to a city that is going to be under attack."
Since March 2011, Syria has been hit by militancy it blames on some Western states and their regional allies. Backed by the Russian air cover, the Syrian military is engaged in an operation to rid the country of ISIS and other terrorist groups.
The foreign-backed militancy has left millions of people homeless. According to a UN report more than 400,000 people have been killed in the Syrian conflict.
