I would not put it past the US to ask Cuba, let the Cubans donate then send the western weapons replacement, intercept their own ship, impound it and declare it to violate the embargo thus screwing Cuba over.
What Cuba should do is say this is their concern, ask the US to send replacement western weapons first before they send the Soviet weapons then not send the Soviet weapons (inventing reason if they want), what is the US going to do? Embargo them harder?
