If the US actually tries to start a war everyone is fucked because nukes will fly and end all civilisation. Their longterm strategy is to build Europe-MiddleEast-Asia-Africa into one interconnected landmass of infrastructure in such a way that cooperation is most beneficial and to push the US out through support of sovereignty. Their short term strategy is to be such a large productive force that others are too dependent upon them to really fight it.

As for global communism. They do not have global revolutionary strategy. That's up to socialists in each of their own countries i suspect as it conflicts with ensuring their support for national sovereignty against US dominion is authentic.
