ELI5: How is Russia able to do all the naughty things they do without much international intervention?

I have a feeling in the last few years, Russia has done quite some things that are frowned upon by the rest of the world, i.e. annexation of Ukrainian land, now the capture of Ukrainian ships and (supposedly) meddling with US elections. Of course nobody wants full-on war, but it still feels strange.

No country wants a serious fight. Russia would be a actual threat. Because of this you also risk other countries that might not have been a issue becoming one as they join up with Russia or take advantage of others weakened by them. 

It's the same reason no one intercedes the US or China as well.
