The thread I started over at DefTalk.
Venezuela supplies 2 million barrels of oil to the US a day. The US is not going to attack Venezuela. The US economy would immediate crash and thousands of Americans would die (oil is the blood of most countries infrastructure).
Really? Do you not think that the US would respond to unwarranted agression against a close ally, by a man who is already on the US's "naughty list", in the Americas? Betting against US action if this goes hot is a surefire way to get burned yourself.
The Columbian government would easily lose if a war breaks out. It would be the rich vs the poor in Columbia, rich people do not want to die. Plus Venezuela would help FARC. It would be quickly over, through short military action plus a coup style change in government. Once war breaks the current government will be attacked on all sides, even within for starting the chain of actions. I predict, this is actually what Chavez wants.
The Columbian Army is certainly better trained and experienced that the Venezuelan Army (10 years of US Special Operations training, 30+ years of combat against FARC and others), has 7 divisions of well-trained infantry, and is defending mountainous, forested terrain. Militarily they have the advantage. Politically, support for FARC is little to none. There will be no popular uprising, if that's what you're implying. The Columbian people view FARC as a bunch of criminals (which they are).
...especially when the Columbian government started the chain of actions.
How? Chavez was the one who "came to the defence" of a country that didn't ask for it. Granted crossing into Ecuador was not a good thing to do, but there are precedents for hot pursuits of guerillas.
But as I said, I doubt that this will go anywhere. It'll probably vanish by this time next week.
