With the coming of hydrogen bombs in the mid 1950s and intercontinental missiles in the early 1960s, cities became defenseless, for they could be annihilated within minutes, with no warning and no chance for evacuation. But that was not the case in World War II. The peaceable civilians had the knowledge and opportunity to get out, and most of them did so. If anyone missed the message from their own government, they could not fail to catch one of the hundreds of millions of leaflets dropped by Allied planes warning them that a real raid was imminent and they should evacuate immediately. In late 1944 American intelligence discovered that in Berlin, "Evacuation has been very thorough and the city now is relatively empty." In peacetime, Berlin had four million population; now it had scarcely one million, many of them foreign forced laborers. | With the coming of hydrogen bombs in the mid 1950s and intercontinental missiles in the early 1960s, cities became defenseless, for they could be annihilated within minutes, with no warning and no chance for evacuation.
