Take a deep breath, you are jumping at shadows and telling everyone that "they" are out to get us.
Thieves are thieves, organized crime is organized crime. You think there aren't major criminal organizations in the US committing ransoms in other countries?
Previous poster isn't wrong that the Russian government turns a blind eye to these kind of things as long as it doesn't target Russian citizens; same with China etc. This isn't especially controversial, and anyone involved with these kind of things will tell you this.
Calling this an "act of war" is of course hysterical.
What an absurd statement. And what do you suggest we do? Attack them and hope they don't respond with nukes?
