Theres a international war going on right now in Canada... idk what u guys are talking about.... There has been several cases of international groups fighting for controll in places such as Germany with the Ndrangheta.
i agree that the Russians are not as powerfull as once believed they could get too. but the Ndrangheta has proven to be international and deadly.
To be honest, Russian crime groups have shown to be very powerful. Such as biggest groups like Solncevskaya have contacts within Kremlin and also sub-groups are based in many other countries or they just force other smaller groups to go under them like it has happened with Haritonov Brigade in the early 2000's.
Different groups have gained contacts in government structures like Vor V Zakone Vyacheslav "Sliva" Shestakov who was caught discusinng with Estonian Security Service agent in a Latvian curort city restaurant. The agent later was arrested and prosecuted for it.
Deadly? There's a lot of conflicts going on between the groups themselves in Russia and they bring it out in Europe too. Paddy Doyle an Irish criminal in Spain was killed by Russians in 2008. There's been several Russian hits done in Latvia and Europe overall.
You can't compare the power between this groups as we don't have the whole information on every single crime group linked there. But saying Russians are not powerful is a weak fact.
