No maybe about it, "Safe Zones" were designed to group non combatants as Human Shields for areas to recruit, train, retrain, reorganize and supply "Moderate Rebels" (mostly ISIS commuters), and to supply propaganda fodder for Globalist - Socialist "Human Rights" shill organizations.
Then install US Troops at high risk with foul ball Rules of Engagement.
End result: prohibition of Russian air strikes against ISIS and Turkish (if necessary) targets, loss of US Military personnel to any Muslim's whim, and further destabilization of Syria.
Safe Zones should be installed in Saudi Arabia entirely at the cost to and supervision of the Saudi's.
Nobody is safe in Syria Ukraine or anywhere else as long as THE USA continues using extremists to fight set up proxy wars to compete over economic interests
and to let die-hard Cold Warriors like McCain and Graham poke Putin
all at the expense of chaos, war and thousands of deaths and millions of refugees
