With all the acts of terrorism all over the world, the mass shootings and killings, the general unrest in many European countries, the war in Afghanistan, Syria, Iraq, Yemen, Somalia, to mention a few, Al Qaeda, ISIS, Taliban, North Korean nuclear threat, Iran nuclear threat: " the world has never been safer " ?
Of course. Let's look 30 years ago. The Soviet Union and the US were threatening each other with nuclear annihilation hence there was a possibility that a substantial fraction of the global population would die in a nuclear holocaust. The acts of terrorism are extremely sparse and kill very few people compared to past wars. They are just the acts of oppressed third world people trying to respond to Western meddling in the Middle East. While North Korea is not really a threat, they just have some nuclear weapons for self insurance. It's threat is not remotely on the same order of magnitude as the Cold War was. The only bloody thing that happened in the world over the past 10 years was the Syrian civil war which killed about half a million people. That's bad but wars in the 20th routinely killed more than a million when the world's population was much smaller. WW2 for instance killed 3% of the world's population or equivalent to 220 million deaths in proportion to the world's population today. Such a death tool would be unthinkable today.
Somehow I doubt that people worry more about being insulted.
Maybe they should be, as insults, one way or another, lead to violence.
The connectivity that you mention has it's perks, but is artificial and has led to the desensitization of a whole generation.
For those who have aspirations of achieving peace through talks and diplomacy, the trend is more towards gloom and doom.
You may disagree, but that's the real world we live in now.
You appear to not know much about history of violence. Anyway the worst thing it can happen today would be if China started an arms race and the US decided to confront China and tensions would built up to a point where WW3 would occur. However this situation is very unlikely for the following reasons:
1) Today we have nuclear weapons and these weapons means that great power can easily inflict tremendous destruction without great cost, which means that if WW3 would happen all major powers would be annihilated and hence no country would be rational to enter in such a conflict.
2) Even if WW3 could happen and countries could deter each other from using nuclear weapons the fact is that Chinese leadership understands that the costs of warfare are always much higher than the benefits. The lesson was learned by Germany with WW1. And WW2 only happened because of certain circumstances in WW1's ending were a bit ambiguous making Germany wanna try again and with a leader crazy enough to try again despite the massive losss of life in WW1. Overall the great powers today are conscious that big wars are stupid.
3) Geographic conditions make it hard for a bloody war to happen again. WW1 and WW2 managed to be so bloody because they involved major powers on the same continental landmass (deaths from countries outside of Eurasia were minor in both wars). Today the great powers are geographically isolated from each other by oceans and siberia so it is virtually impossible for a bloody conflict to emerge like in WW1.
The violence of a major war is much greater than the violence of terrorism (statistically insignificant) or criminal violence (which has been decreasing globally according to a secular trend) and there is very little risk of major war happening in the world today.
