[Just me or does this read as if it’s meant to cheese Trump off and embarrass him into action?]
The author supports Obama’s deal with Iran. He is pointing out that if Trump proves unwilling to strike Iran regardless of what it does to its Arab neighbors, Iran will complete its nuclear weapon and start using it to improve its situation in the region. For instance, a nuclear attack on neighboring oil fields will spike oil to $200, thereby making it a lot easier to sell sanctioned Iranian oil to desperate 3rd World countries looking to keep their economies from going into depression.
