Debka most recent report claims that the relocation of the chemicals have taken place under common Syrian-Russian control.
If true, & given the assertion by Lavrov that Bashir Assad is not going to flee & that no one will win the war, then Russian military presence in Syria may have two objectives. First to remove one reason for US intervention by claiming the chemicals are in "safe hands". Second, to keep the Assad regime alive, even if it will be over a small part of Syria.
Should that scenario materialize, then one can expect to see Al Qaida like attacks on Russian interests inside & outside Syria.
