This militarization is starting to look really dangerous and seems poised to break the relatively peaceful streak that the Western Hemisphere had going.
The Colombian government has announced it is building a new military base on its border with Venezuela and has activated six new airborne battalions.
Relations between the two nations are at a historic low with Venezuelan President Hugo Chavez already telling his generals to prepare for war.
He moved 15,000 more troops up to the border, accusing Colombia and its ally, the US, of planning an attack.
A BBC correspondent says the potential for conflict is heightened.
Colombian Defence Minister Gabriel Silva announced the formation of a new base in La Guajira in the north, near the Venezuelan border.
At the same time, the Colombian army activated the new airborne battalions, which are equipped with US helicopters.
The helicopter fleet, made up mainly of Blackhawks, now numbers 120, making the Colombian Army Air Corps the best equipped and most experienced in Latin America, the BBC's Jeremy McDermott in Colombia says.
Again, much of this is linked to paranoia surrounding the new US basing agreement with Colombia.
