Such a warning system would have been sufficient back in the 1950s and early 1960s when the attack would have used bombers to deliver the bombs (I remember the Civil Defense siren tests when I was a kid). However any attack now will almost certainly use ICBMs which would arrive too soon for any such warning to help.
The Civil Defence siren system has been replaced with the Emergency Alert System that interrupts TV and Radio broadcasts with warnings of various natural disasters. This is one benefit that spun off of the Cold War.
Why was Pearl Harbor attacked without warning also? You will find online that we dropped leaflets over the cities before we destroyed them. I'm not sure if we actually did drop leaflets, but if we did, we did not drop them on Nagasaki or Hiroshima. They were dropped on other cities after the destruction of the others.
Wake Island was attacked next.

Attacked Pearl Harbor and atomic bomb was dropped on Hiroshima
Leaflets were dropped over Japan warning them of a "big bomb" but not naming it as an atom bomb. They were told to get their government to surrender or the big bomb would be dropped. The Military Leaders were asked to surrender again.
Yes, they are but are called bomb sirens
They went into bomb proof basements and shelters. They also did black outs, which meant that the threatening air pilots couldn't see where they were trying to bomb. Britain had sirens which were triggered by the movements in the air to tell the people that they were about to be attacked from the sky and to get ready and safe. Many sandbags were used to protect old buldings and monuments.
no it doesnt
When the Air Raid sirens stop and the bombs stop falling it is safe to leave.
Never, Britain has never been attacked by a nuclear (atom) bomb.

If you have the question that relates to how many sirens mean a tornado, the answer is... It kind of depends where you live because I know that some counties in Wisconsin only have one siren and that is the tornado siren so like I said it depends where you live. Another type of siren is the war siren or some people know it as the bomb siren. That means that people are trying to bomb you. And then there is the Wildfire siren. That means get out of the area because a wildfire has started near you, but that is mainly in the southern states like Arizona, New Mexico, and Texas.
