They might have them, but can they use them? Besides, wars are won on the ground not in the skies.
I assume that given the fact they have been flying them for years, then yes they can "use them". Air superiority is key in any conflict. I've no idea what the hell Chavez might actually do, but if this isn't just bluster and he actually does something, the likelihood will be it will come from the air.
Say what? You are kidding right. You are in a world of hurt without air superiority.
With this comment you have proven yourself to be a really ignorant person with respect to military history.
