History is more than the Boxer Rebellion.
Now, how are the Chicoms going to treat other people with full thermonuclear warhead capacity mounted on ICBMs?
I'd think they'd start treating them respectfully right off the bat ~ any more traditional Chinese arrogance and things will not go well.
Why did you think the US protected the Dowager Empress??? It was not done for charity purposes. The US realize that if the Empress died, the reform movement which controlled southern China and kept the Boxers out can move north and take Bejing. How is the US, Japan and the West going to take advantage of a weak China head by more competent modern leaders? Old Asian strategy, never kill an incompetent general or leader, he might be replaced with a good one. For the US keeping the Dowager Empress alive served that purpose plus it was also good PR.
By the way, the southern reform movement mentioned eventually overthrew the Manchus and established an American style republic in 1911. The leader of the movement became its first President, the person was Sun Yat Sen. Ask yourself a dumb question, back in 1900 the US felt that China needs to be modern and civilized like modernized Japan, why did we protect a monarchy in lieu of supporting the southern reform movement in China modeled after Western republican ideas???? Despite our democratic and modern ideals, money and greed still talks. It happen back in 1900 and it still happens today.
