Iran on the move?

President Mahmoud Ahmadinejad of Iran is visiting Venezuela and its rogue president Hugo Chavez. I wonder why? What have these countries in common besides having Presidents that harbour a hatred of the United States?
Could we soon see North Korean made rockets, carrying Iranian nuclear warheads located on the Venezuelan mainland. Ostensibly, according to any treaty, they would be there to defend the South Americans from attack by the United States but in reality they would be there as an insurance policy in the event of an Israeli attack on Iran.
The Shahab 4 rocket, either two or three stage could reach Florida from Venezuela. With this arrangement in place, the Iranians could tell the Americans that any attempt by them directly or by the Israelis to attack targets in Iran would trigger a response that would directly impinge on US territory. If successful, millions could be killed. They would, therefore, feel free to act with impunity in the Middle East.
