In war, just think about how many babies are conceived from occupying soldiers – regardless of which war it is. Sex is a very high stress reliever for the male of the species. Don’t count out a large number of pregnancies. Prostitution flourishes in wartime! If wives and girlfriends are “available,” it simply makes it all the “easier.” I am NOT endorsing that from a moral position, just reflecting what has historically been reality on a very large scale.
Regardless of whether someone wants to attach religious significance to this or not, the warning could not seem much more relevant today:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter … :
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
