Not anti American, perhaps, but certainly not pro American in this case, and the fact that he consulted with the Russian ambassador but not American officials, before making his decision certainly suggests he is more pro Russian than pro American. Add to this fact that his preposterous "peace plan" which would give Russia all the Ukrainian land it occupied without regard to any relevant treaties or laws, and it is plain Musk is pro Russian. If the US were actually fighting in this war, his decision to protect the Russian Black Sea fleet that was firing missiles into Ukrainian cities could qualify as treason.
