Is Trump's buddy Putin finish?

Is Trump's buddy Putin finish? I say this because he has withdrawn from Syria. It's my understand that oil is main source  of revenue for Russian,however to make money the price of oil has be $100 a barrow  it's about today like $30. Also a few weeks in the Wall Street Journal it shown cars sale, everybody is worry about China however cars were only down 1 or 2 percent in China, but Russian it was down 10 percent this is sign of economy in real trouble.
