And why not? After all, Hitler visited Austria after the Anchluss. Of course, Ahmadinejad may be jumping the gun a bit as far as that is concerned, but he is certainly doing all he can to bring into being a Shi'ite client state in Iraq. From [1] Iran Focus, with thanks to JE:

Tehran, Iran, Jun. 27 – Iran’s hard-line President Mahmoud Ahmadinejad will soon travel to Baghdad to meet and hold talks with Iraqi President Jalal Talabani, the government-run news agency Fars reported on Monday.

The report quoted an “informed source” as saying that Ahmadinejad would hold talks with several top Iraqi officials.

He would lead a large delegation to Baghdad, the report said, adding that several political and economic agreements would be signed between the two states during his trip.
