These so called "rebels" are nothing else than the same ISIS thugs.
They were created by CIA, like ISIS and Al-Qaeda are.
US is A DEVIL of imperialism.
US is trying to control the world, thru intimidation of Western Europe, using all means necessary for that, including waves of terrorism directed by CIA thru ISIS, and flooding western europe with millions of arabs and thousands of terrorists among them.
After the first wave of terrorist attacks, Western Europe has finally succumbed to american threats and now a new american PUPPET by name Boris Johnson, has become a new mouthpiece for Washington, throwing dirty insults against Putin. There is a Price tag for that. And the West will pay it. Price tag is a counter economic sanctions against the West.
Russia didn't use it yety, but when it starts using it, the West is going to feel it big time.

putin wants to increase russian power in the middle east.
it is for this reason that he has allied with iran, hezbollah, syria,
and most recently, with turkey.
putin will not stop murdering syrian civilians util some power
prevails in stopping him.
the west has allowed itself to become weak and narcissistic,
without the necessary understanding of foreign cultures and
societies. american leaders thought that putin could be
civilised. they were wrong. putin wants to remain putin.

Boris Johnson is acting like a jerk , his words are inflaming an already volatile and dangerous situation .

Boris Johnson stupidly ,extremely stupidly ,threatens Russia ,which is not wise .
