Russia would cross “a red line for the United States of America” if it were to base nuclear capable bombers in Cuba, a top US air force officer warned on Tuesday.

“If they did I think we should stand strong and indicate that is something that crosses a threshold, crosses a red line for the United States of America,” said General Norton Schwartz, nominated to be the air force’s chief of staff.

He was referring to a Russian news report that said the military is thinking of flying long-range bombers to Cuba on a regular basis.

The newspaper Iszvestia on Monday cited an unnamed senior Russian air force official in Moscow as saying that Russia may start regular flights by long-range bombers to Cuba in response to US plans to install a missile defense system in eastern Europe.

A White House spokeswoman declined to comment on the Russian report because there had been no “official response from the Russian government.”

Conducting long-range bomber patrol to Cuba would signal a reawakening of military cooperation by former Cold War allies Moscow and Havana, and recall the 1962 missile crisis that brought Washington and Moscow to the brink of war.
