Putin did save Christians in Syria. If you meet any Syrian Christians, they’ll tell you
God can use evildoers to accomplish his ends—even good things. Including Putin and Assad.
But by that logic, this is also true:
“Muslim Refugees are Converting to Christianity in Germany”
That is so much B.S. Putin was only in Syria to protect Iran's interest in Assad, and to protect the use of Assad's warm water port for use by Russia. Russia was not there to fight ISIS, except the limited parts of ISIS that were a threat to Assad. If you followed what Russia did in Syria, they were not on some mission against ISIS. Any Christians helped were collateral, and very minor. You are being sold a bill of goods.
