Farc and Venezula

I found an interesting article here : http://www.dailymail.co.uk/pages/live/articles/news/worldnews.html?in_article_id=524314&in_page_id=1811

The article discusses the current situation in South America. Specifically, the Colombian government recently killed a leader of the Farc who was hiding just across the border in Ecuador, without Ecuador's permission. This has angered Hugo Chavez and Venezuela; possibly because they fear similar action in Venezuela. From what I can gather, Chavez is a huge supporter of the organization and there seem to be fairly clear ties between the Farc and his country. Recently he has attempted to change the world view of his relationship with the the Farc to the of mediator instead of collaborator. He claims that the recent release of Farc hostages is a direct result of his requests from the organization. In response to the death of the Farc leader Chavez has moved a large portion of his military to the Colombian border threatening war.
This is perhaps one of the most extreme examples of state sponsored terrorism that I can recall. To my knowledge Iran has never deployed its own military in response to an attack against Hezbollah, though it has threaten to become involved when Israel chases the terrorists across the Lebanese border. This article claims that America supports the Colombian efforts. In the wake of shattering relations with Venezuela, the US-Colombian relationship has evidently strengthened. Currently the US has a small force in Colombia working to hinder the drug trade.
