legally as naked aggression and an act of war. US sanctions and other racketeering scam theater work on its quisling regimes and
other weak countries. They don't work on Russia and China.
The fact that the US backed off after a couple of hundred Russian and Chinese specialists arrived in Venezuela implies it will not be
engaging in naval warfare with Russia and China. So there will be no blockade. America needs some "international coalition" as a
fig leaf for such action. No such coalition will form. Even in Latin America there is not much appetite for Uncle Scumbag's chode.
