Fuel smuggling out of Iran isn't new. Historically Iran doesn't seize the smuggling tankers. They have in the past responded to usa seizing their ships by siezing american ships. Clearly this is not that. So what has changed? What is new is usa doing piracy in the Caribbean. So these tankers being seized is an indirect consequence of america's actions.

The mental gymnastics you are going through to say "nothing to do with usa" is really quite funny considering the comment I responded to called this post Cope.
