In addition to Venezuela owned Citgo, we also import distillates from Venezuela. Additionally, the HOVENSA refinery in the Virgin Islands is co-owned by Venesuela. This refinery, is dedicated to US demand.
The refineries in the West Indies are there because of more relaxed environmental laws.
Bias note: Citgo charters one of my company's ships at c.a. $40,000/day.
Fun fact: 2 weeks after hurricane Katrina, I was working on a Shell (owned by the Dutch Gov, btb)-chartered ship. We took 150,000 bbl of diesel and 90,000bbl of regular unleaded from Delaware to the mouth of the mississippi, then were ordered to anchor, where we sat for 2 weeks. Then we brought everything back up to NJ.
My point is that at least a mad dog like Chavez will have the decency to stab one in the FRONT. It's dirty Europeans like the Dutch that will throw us under the bus.
