In my opinion, this is another ''cold war'' in progress, and Russia and USA fight over influence in this areas(specially Ukraine is the target).
Middle east conflict is even more complex, since 1948 when UK left this territory and UN was unable to find working political solution for this area.
Now, I don't think that we will see solution to this conflicts soon because it seems nobody is really interesting in peace bnow, after xso much bloodshed.
