From your safe place behind a safe computer, you can say that.
Go ask the people in Syria if they feel like they are taking part in a "more humane and less deadly conflict".
That's like saying "Global Warming isn't true because it snowed today!" The Syrian conflict is a horrific, awful anomaly. Even then, it's pretty restrained by historical standards and more than offset by the otherwise tranquil world scene at present. It should also be noted that much of what Assad is doing isn't involving guided munitions because he just flat out doesn't have them. And his opposition has no airforce at all.
Compare that to 100 years ago and a similar conflict probably would have resulted in flat out genocide and deliberate extermination of 70% of the population. Current estimates are that about 0.5 - 2.5% of the population has been killed in the conflict. That's comparable to the American Civil War, but the vast majority of the world is at peace so as a percentage of world deaths it's pretty tiny. The Syrian conflict is almost notable because the world is otherwise so peaceful.
