Is it illegal to send cars to Cuban Catholic Priest in Cuba?

I am planning on sending cars to Cuba through Belize or Venezuela in because it cost hardly anything.Some people say it is unethical but I find it beyond demonic to not support my superiors in Christ and to fulfill his last comandment ,isnt is digusting to have a Embargo that hurts not the Goverment of Cuba not even a tad bit ,but is destroying a country which has enough resources and income to support its people for many decades perphaps centuries with abosolute poverty.
