In fact if you read left-wing press, it has been almost a constant in the last months: first was the expansion of the military concessions in Colombia to the USA, including legal immunity and total access to Colombian bases, then was the rejection by Guyana of allowing a US military base in its territory, then the expansion of US military operations in Dutch and British colonial outposts in the area, notably Curaçao and Aruba, just offshore of Venezuela... and also some border tensions, evaluations of the overgrown Colombian narco-army, almost as large as that of Brazil, rumors of coup in Paraguay, effective coup in Honduras, followed by US recognition after farce elections.
Even if there is no incoming war, the situation is clearly very tense.
Now President Chávez has declared that Caracas really expect an invasion at any moment. In fact they expect an intelligence maneouvre to create a "false positive", killing some Colombian peasants, dressing them in military fatigues so the appear FARC members and moving them into Venezuelan territory in order to create a pretext for further escalation or even outright war by pretending to have destroyed a guerrilla base in Venezuela.
The Venezuelan government has also denounced the mediatic criminalization of the Bolivarian Republic, by means of repeated false accusations of sponsoring terrorism and drug trafficking, creating the propagandistic impression that Venezuela would be some sort of enemy of humankind, when in fact it's just a regular democratic republic with socialist tendencies (and that's what they really fear and want to destroy: Socialism).

As European I believe that is particularly important to denounce the complicity in particular of the Dutch government, which is behaving as a total lackey of the USA. And I would call for a boycott of Dutch products in case that Venezuela is ever attacked from the Dutch colonial remnants.
It is also important to emphasize that the only narco-state in the area is Colombia and that the main drug-trafficking cartel is the DEA. So if the USA would truly like to declare a war on drug trafficking, they would have to attack Colombia and their own police forces.
