(CNN) -- The United States is pushing for what would become nuclear wars against Iran and North Korea, former Cuban leader Fidel Castro said in a rare televised interview Monday.
Castro blamed the United States, not North Korea, for the sinking of a South Korean ship that killed 46 sailors. The incident was orchestrated to stir conflict in the region, Castro said.
The former Cuban leader, who hasn't appeared in front of the cameras in 11 months, said he was disappointed that China and Russia didn't veto a U.N. Security Council resolution for additional sanctions against Iran for its alleged illegal nuclear program.
Iran, he said, has been building up for a confrontation for 30 years. If the United States attacks Iran, it will meet a resistance unlike anything it faced in Iraq, Castro said.
"A war there can't avoid becoming nuclear," Castro said.
