Yes that was the war to end all wars of my generation .
It was of another time , I fear that we haven't learnt any lessons from it .
I think at least China has learned a lesson. How to get resources wthout bombing a country into submission, like America went for oil in Iraq. China wants our iron and coal reserves. It buys them. And it uses its huge population to outsell most nations in goods such as TV's, clothes, and many other manufactured goods. So its got plenty of money to spend when it wants something.
Australia, and America, and probably a lot of other countries, like Greece, have huge borrowings, while China acts as the lender. So quietly, quietly we, and the other countries, are becoming economically dependant on China.
As long as they don't use this to put the 'hard word' on us, everything is OK. At least they won the 'war' for our resources without invading us with guns and bombs, as did the Japanese in WWII! But Rio and BHP are putting their prices up and so the Chinese are threatening to stop buying iron ore from OZ. Then where will we be! I think we get a lot of revenue to pay off our debts from iron ore sales to China.
Meanwhile America seems to be bruising for a war with Iran. They think it is OK for themselves to own hundreds of nuclear warheads, but no other country is allowed to have nuclear weapons! We can only watch on and hope they don't set off another Vietnam or Iraq, or even worse!
So as well as having all of these environmental problems brewing, due to over-population -species extinctions, extreme weather events and sea levels rising, we also have some tricky relationships developing between the world's super powers.
We live in interesting times!
