Iran's agenda is to expand its borders, and it is openly saying so. Yesterday a high ranking general bragged that Iran is extending its boundaries "from the Red Sea to the Mediterranean." It is a boundary reminiscent of the First Syrian Empire founded by Cyrus the Great in 550 BCE.
Last week an Iranian general pledged to fulfill a vow made by his country's 'Supreme Leader' two years ago. A new army has been established to destroy Israel, "Allah willing," in 23 years.
