Much of the conflict resolves around energy. Energy is bascally all of Russia's economy. Europe depends on the energy supplied by Russia and Russia depends on the income paid by Europe.
Europe would like to have alternate energy sources so as not to be dependent on Russia. Qatar, for example, has plenty of gas, but there is not a pipeline connection where they can export to Europe. It was their desire to run a pipeline through Syria, but Assad, an ally of Russia, refused. Coincidentally (wink, wink), massive revolts broke out in Syria where jihadists and weaponry were supplied by Qatar and Saudi Arabia (both allies of the US).
According to the US, Assad is a human rights violator and needs to be removed. But the fact that Saudi Arabia and Qatar leaders are even worse human rights violators doesn't stop the US from selling them billions worth of military weaponry.
Russia tried Western style democracy under Yeltsin, but because the rule of law did not exist, the country fell into anarchy and the already low living standards even got worse. Under Putin, a semblance of law has been restored. He is very popular, and the country is doing better overall. But now that Putin is in power, the US no longer has as much sway over Russia. Hence the continued pressure by the US on former USSR Satellite states to join NATO.
Our foreign policy meddling has backfired on us in Iraq and Afghanistan. LIbya, under dictator Ghadaffi, actually possessed the 2nd highest living standard in Africa. Now the country is in shambles and Al Qeda flourishes there. Our miscues in Eastern Europe are going to backfire on us as well.
