Was there a plot to kill Bush in Chile?

Dr. Jack Wheeler, in an article in his website To The Point, quoted here in WorldNetDaily, says that many angry voices in Washington would dearly like to know just that. Why, they ask, did Chilean security forces--in a complete violation of every understanding they had with the President's advance team--try to separate Bush from his chief bodyguard? Why did they balk at the installation of metal detectors, in violation of the standard procedure that every foreign dignitary who entertains a President of the United States clearly understands? Add to it that the current President of Chlle, Ricardo Lagos, has always been a socialist, and is chummy with Hugo Chavez of Venezuela, and you can't help wondering whether Chavez and Lagos actually plotted to assassinate Bush in a manner uncannily similar to the assassination of Gaius Julius Caesar.

In fact, Gaius Trebonius, the actual instigator of the plot to kill Caesar, separated Mark Antony from Caesar at the critical moment when the latter was about to enter the Curia Pompeia to preside over a session of the Senate--ironically, one where he intended to lay down his dictatorship in return for an imperium and an assignment to attack the Kingdom of the Parthians--which nation we call "Iran" today. A leader separated from his bodyguard, at a moment when a troublesome Middle Eastern nation is the center of the attention of that leader's government, which happens to be the then-current superpower--the parallels are frankly chilling.

UPDATE: Colombian rebels definitely did try to kill President Bush while the President was on the Colombian island of Cartagena. Might Lagos of Chile have sought to collaborate with them? Birds of a feather flock together, after all.
