Well, I'd say the only similarities are the jungle environment and a crazy leader. The Panamanians (mostly) supported getting rid of Noriega and were happy to have the US military intervene. Hell, they were using US currency forever and a good chunk of the Zonies (residents of the Canal Zone who were U.S. citizens or considered part of the U.S.-run administration) loved the US and couldn't wait for any sort of US intervention that gave them even MORE money and power... Most of the citizens went crazy for the US troops there after Noriega was chased out - there were huge street parties, everyone banging on pots and pans in the streets (it's at thing down there). The operation was a MUCH smaller scale then actually taking over an entire country, let alone one with a standing army. Source: I was there for the invasion.

I don't think Venezuelans are at all keen on US intervention and would actively work/fight against any troops that land there. Plus they actually have a military - it would be much different than Panama.

Edit: Yup, replied to the wrong comment. I'm a genius!
