Plenty of friction indeed, but the big difference is that (almost) nobody wants to go to war. Just before WW1, everybody was itching for another war. China definitely does not want war with the US; they want to expand economically. Nobody in the EU wants war over anything. The US has always been the most eager to go to war, but even they seem to have learned that wars are expensive and have little benefit. Russia wants to control (pieces of) their neighbours, but again without an actual war the EU or NATO. Turkey is primarily interested in crushing anything that might start to look like a Kurdish state, but also doesn't want a war with a big player.

Wars today are mostly cold or proxy, and rarely direct.
