No body call US as a big brother without any reason . US is the reason for many countries to be safe. Including Japan, South Korea, India, Philippine. USA has made mistakes in the past but they work on it ( and I know they are still doing mistakes). I feel Putin is using everything for his political benefit. Rubel has fallen so low and the economic crisis made Russia desperate. So when he started bombing in Syria he bombed anti Assad forces in the name of ISIS. Still his major bombing is against them. But after the aircraft was bombed he is bombing some parts of Raqqua but that's not his main target. Putin is trying to install confidence in Russians. It's pure politics.
