Economic (where the sanctions regime has not only failed but derailed the western global banking system hegemony in that sphere and spurned economic boom in Russia)
Political (Georgia, Armenia, Ukraine and less successful attempts in Belarus and Russia) via proxy NGOs with dark money funding and no transparency
Military (providing funding and weapons, volunteer mercenaries and now "military advisors" and soon NATO boots on the ground - conserving their own troops using these proxy forces at least till after the election in the US)
Its not working out how the US hoped but only because they are incapable of thinking things through and over the top hubris set themselves up for this epic fail.
