Using Wiki data there does appear to be a reduction in % of world population killed in war over time.

http://en.wikipedia.org/wiki/List_of_wars_and_anthropogenic_disasters_by_death_toll

The high and low death toll estimates were averaged for the dependent variable, and the mid-point year of the war period was used as the independent variable. Regressing mean estimated % of world population killed in war vs year:

The regression equation is

mean est % world pop killed = 9.94 - 0.00466 avg year

Predictor       Coef   SE Coef      T      P
Constant       9.938     2.693   3.69  0.001
avg year       -0.005     0.0016  -2.97  0.007

S = 3.26307   R-Sq = 29.6%   R-Sq(adj) = 26.2%
 

>>Significant; year explains 26% of the variance. However a plot suggests though war has become less deadly over time, it is more frequent.
