After Russian President Vladimir Putin threatened to use nuclear weapons in Ukraine, the West has been debating how he would respond if it happened.

He said that if the territorial integrity of our country is threatened, we will use all available means to protect our people. Russia has many weapons to respond.
Analysts are not convinced that the Russian president is ready to become the first person to use nuclear weapons since the US bombed Japan in 1945.
AFP spoke to several experts and officials about the possible future scenario of a Russian nuclear strike.
