The funny thing about the supposed Iranian influence in Latin America is that for at least the last ten years, every so often Iran feels the need to send a government official to launch a "new chapter" in relations with the region. It is doing so now.
Countries that have influence don't need to relaunch. They just launch once and then go from there. Also, countries that have influence don't need to blame Israel for the fact that all their launches fail.
Iran has been growing increasingly close to Latin America in recent years, but has accused Israel and other countries of undermining its emerging relationship with the region. “Certain regional states have also joined the Zionist regime and display a wrong image of Iran in line with Iranophobia plots,” said Takht-e-Ravanchi to Iran’s Fars news agency.
Not surprisingly, Telesur reports this uncritically without noting not just the anti-Semitism but also how ridiculous the argument is. Iran's image comes from Iran's own actions, including past terrorist attacks in Latin America.
