Ten years ago, four airplanes were hijacked in the USA. Two of them slammed into the World Trade Center in New York City, causing both towers to collapse.
On the financial side, the 911 attacks cost the USA 100 billion US dollars. But the following wars were estimated to cost ~4,400 billion - to the USA alone. That is roughly 44 times the direct costs of the original attacks. It does not even start to account for the costs to the other nations.
The 911 attacks were due to previous conflicts. And the current conflicts will not stop today. As rich and powerful as the American military is, it will not be able to truly subdue its enemies. It does not even know exactly who the enemies are, let alone where they are and how to stop them. Its enemies are not going to stop themselves either. As angry and determined as they are, they are not able to really destroy the USA in the foreseeable future. If anything, the conflicts will continue and just get worse, the way it is going.
What, then? If neither military might nor devious terrorism can provide the answer; can people come up with better ways to get us out of this killing frenzy? Can people at least try to identify the vast majority of the people who do not really want to kill each other, distinguish them from the die-hard incorrigible extremists, and see if something can be done to help those who simply wish to live in peace?
For the sake of the human race, would you please try? For practical reasons, would the ones with the power, the upper hand, take the initiative to find a better way? For those who believe in God, whatever you call Him, wouldn't God want you to do that?
