Neither.
Putin eagerly proclaimed his Christianity in a NYT Op-Ed awhile back.
Putin also vocally decried Christian slaughter by Muzzies in Egypt and defended Egyptian President al-Sisi in his efforts to drive the Muslim Brotherhood out of Egyptian politics. Putin backed al-Sisi's vow to rebuild the 63 churches torched by Muzzies who rampaged over Christian homes and businesses.
==============================================
Putins impressive debut on the NYT op-ed page announced his personally-held beliefs thusly: "......when we ask for the Lord's blessings, we must not forget that God created us equal."
This is something every Christian believes---an article of faith for Christians.....and, not coincidentally, the bedrock of our constitutional republic........
==============================================
We, the people, know we will never hear Obama say anything even remotely religious.

Some say that when Putin professes Jesus as the Son of God and kneels confessing Him as Lord of his life and Messiah of Israel, they will believe some of what he says.
Christ admonishes us not to judge others lest we be judged. No one knows what's in a person's heart.
Besides, we don't know that Putin hasn't professed Jesus as the Son of God and kneels to Him as his Lord.....he doesn't have to do this publicly.
