Putin Dismisses U.S. Nuclear War Fears as 'Nonsense,' But Warns Russia Would Fight Back

Putin says suggestions of U.S. preparing for war with Russia and China are "nonsense" and unhealthy thoughts.

Warns that any war with Russia would be very different from the conflict in Ukraine.

Says Russia and China are not building a military alliance against the West.

Cautions that a war between nuclear powers like U.S. and Russia would be a "completely different story."

U.S. is modernizing nuclear arsenal and estimates China will have 1,500 warheads by 2035, while Russia currently has around 5,900.
