That noise can trigger another world war but for the moment that is only many people's fear. One good thing is starting to come out from this war: a more united Europe, a continent that can continue over the current economical and political problems as one voice for all the European countries. We'll find out in a few months or year if we survive them.
Some bad effect can be the current United States of America won't be so united if Donald duck Trump remains the full 4 years as president, so they should impeach him or whatever other legal action they have in order to stop that guy. And Kremlin can end up burned and glowing in the night if they continue this way. Kremling and many other parts of the world in the worst case.
