This is why the Monroe Doctrine was created.

Russia is still playing in our pond.  They've dispatched nuclear powered and warhead carrying naval vessels to play with Chavez's navy in the Caribbean.  They've announced that they want closer ties with Latin America.  And now, they're offering Venezuela help with developing nuclear capability.  

Yes, they've beaten out a compromise with us to ask for more worthless resolutions from the UN against Iran's nuclear ambitions.  That's not the point.  No, they're making more threats, and nastier ones, by cooperating with our hostile neighbor's nuclear ambitions.

They're also acknowledging that they are getting involved in another Cold War with us: the puppet president has announced that Russia is putting up its own missile defense shield.  

Why put up the defense shield?  Might it be because they know damned well that they're doing, in Venezuela, would have gotten them spanked during the last Cold War?  I don't know if they don't realize that we don't have the political will, or simply aren't sure if we do or not, and don't want to risk the attack.  In any case, forcing them to do the spending is a good first step in the new Cold War.
