Basically, so far women didn't go to war. It was in their best interest to send men to war, to perform some "natural" selection, and be left with the better stallions. Of course, the 20th century saw some changes, in the effectiveness and collaterality of weapons, and in the fact that some women do go to war. But basically, the later represents only a handicap to the armies allowing it. But as long as the war cannot degenerate into a wide scale (ie. involve the USA), or a nuclear war (ie. involve two countries with nuclear weapons), it's green light, and the same benefits can be expected. Even about nuclear war, since we've developed small scale nuclear weapons (and since we can also see that the mid-to-long terms effect of nuclear bombs are rather benign, cf. Japan or Tchernobyl)), I would say that the probability to see a local and limited nuclear war is close to 1.
