I think Putin might try something like that someday but right now he has his hands VERY busy fighting the Moslem terrorists ...
he can’t afford to screw around with more Moslem terrorists than the ones he already has to contend with in Syria and inside Russia
we will see what the future may bring, tho.....
A lot of noise here.
Russia is fighting the Islamic State created by those who oppose Assad’s regime including but not limited to the Gulf Arabs, the Saudis, the EU, NATO countries, the US as in Obama, Clinton, McCain etc. etc. and yes, Israel, too.
Israel has consistently used its military forces against Assad’s regime from time to time because taking out Assad would deny the Iranians an ally and base to attack Israel from.
All those who have opposed Assad and undermined his government and supporters have helped create the anarchy in the country that led to the Islamic State being created.
