This news is years old, but at least it is making a rare appearance in the mainstream news media:
The Iranian-backed Hezbollah militia has taken root in South America, fostering a well-financed force of Islamist radicals boiling with hatred for the U.S. and ready to die to prove it.
An extensive smuggling network run by Hezbollah funnels large sums of money to militia leaders in the Middle East and finances training camps, propaganda operations and bomb attacks in South America, according to U.S. and South American officials.
U.S. officials fear the poorly patrolled Tri-border region could make it easy for Hezbollah terrorists to infiltrate the southern U.S. border.
The CIA singles out the Mexican border as an especially inviting target for Hezbollah operatives. "Many alien smuggling networks that facilitate the movement of non-Mexicans have established links to Muslim communities in Mexico," its Counter Terrorism Center said in a 2004 threat paper.
In 1992 and 1994, terrorists linked to Hezbollah carried out two attacks against Jewish targets in Buenos Aires, with Iran's involvement, as well.
The Argentine prosecutor's office said the Iranian president at the time, Ali Akbar Hashemi Rafsanjani, ordered the attack to retaliate against Argentina for suspending nuclear cooperation with Iran.
A warrant for Rafsanjani's arrest remains outstanding, and the prosecutor's office continues its investigation 13 years later.
That's peculiar, given that we have been told incessantly by the media that Hezbollah is a "purely defensive" group formed only in the wake of Israel's original Lebanese incursion.
