Venezuelan President Hugo Chavez has accused the U.S. of spreading cancer among South American leaders.

Chavez said that the U.S. may have invented technology to spread cancer, responding to the news Tuesday that Argentine President Cristina Fernandez de Kirchner has been diagnosed with thyroid cancer. However, he maintained that he wasn't accusing anyone, but just thinking aloud.

It would not be strange if they had developed the technology to induce cancer and nobody knew about it until now... I don't know. I'm just reflecting, Chavez said in a televised speech to troops at a military base, Reuters reported.

But this is very, very, very strange ... it's a bit difficult to explain this, to reason it, including using the law of probabilities, he said.

The Venezuelan radical socialist leader, who underwent a surgery in June to remove a cancerous tumor from his pelvis, apparently wasn't thinking about Venezuela's already deteriorating relations with the U.S.

Chavez supports his wild speculation with the fact that several South American leftist leaders, including Paraguay's Fernando Lugo, Brazil's Dilma Rousseff and former Brazilian leader Luiz Inacio Lula da Silva, have all been diagnosed recently with cancer. His diagnosis and the most recent case of Argentine president's diagnosis, apparently served Chavez enough evidence to reflect on the American advanced cancer (spreading) technology!

Chavez said it was Fidel Castro, the Cuban revolutionary leader, who warned him to be cautious of the U.S. Fidel (Castro) always told me, 'Chavez, take care. These people have developed technology. You are very careless. Take care what you eat, what they give you to eat ... a little needle and they inject you with I don't know what.'

He slammed the U.S. and European governments for crying foul against Russia's recent parliamentary election and alleged that the capitalist nations would do the same to Venezuela in 2012 when he would seek re-election.

They are crying fraud and saying the elections need to be re-run ... They're trying to destabilize no less than Russia, a nuclear power. That's the madness of the Empire, Chavez said referring to the allegations of election fraud against the ruling party of Russia by foreign observers and Russian opposition parties.

I say this because here in Venezuela, the Imperial Yankee, the local bourgeoisie, and a good part of what they call the opposition parties here, are preparing a similar plan, he said.

I call on the armed forces to be alert, on the Venezuelan people to be alert. Because we are not going to let the Imperial Yankee destabilize Venezuela again like they did in the past, he added.
