I'll say this; the last major culture to disappear because they refused to change and adapt was the Roman Empire; that means the USA has approx 250 years left! 
You're comparing American culture to that of the Romans? c'mon now
Why not; Rome thought they were invincible and that arrogance ultimately cost them their empire.
Jack, so you are saying that it's OK to go to war over control of oil? The oil resides on Iraqi and Iranian land; what gives America or any other country the right to invade other countries because they have oil reserves; those countries have the right to sell or refuse sale to anyone or any nation, but that reckoning, the US is a law until itself!
And what right did the Queen have to control Hong Kong and for so long??? or India and every Brittish colonie known to man

The acquisition of Hong Kong was typical of the way in which western countries seized colonies between about 1840 and 1890. In 1839 China stopped the importation by the East India Company of opium, which China complained was having a debilitating effect upon its people. When British and American ships defied the ban, Chinese officials publicly destroyed 20,000 cases of the drug. Faced with the collapse of its Far Eastern operations (for without the opium trade it was not financially viable), the East India Company persuaded the British government, then led by Lord Palmerston, to declare war on China. As a result of the Opium War, Britain gained Hong Kong island. Kowloon was added to the colony after a second Opium War (1856–58) and more mainland territory was taken in 1898.
So whats new?? A country invades another because of peace??

Human kind will kill go to war for money/women and drugs!!!!!!!!!!!!!!!!!!!!
