It's a funny one, because it depends on how you count. In terms of frequency of wars, we seem to be on a downwards trends, with some historical polities (say such as Rome) engaging in war pretty much constantly.
In terms of absolute casualty numbers, the trend seems to be mostly reversed. That's mostly due to the deadliness of modern weaponry as well as the increased state capacity of the combatants.
On the third hand, casualty numbers as a percentage of total population are probably still down, mostly driven by the very large population growth.
