this time the Calvary might find a few issues they have't found in the past.
they've never taken on something the size of China by themselves --- the world will be loath to help. Russia will be very helpful to China most probably.
Now days weapons can hit America at home - that couldn't happen in WW2 or Vietnam. Nor any middle east countries - aside from flying planes into buildings
it's a different game this time
the biggest Empire that ever was ------ was defeated - fell apart -------------- America has had a run - it's quite probable that it's closer to the end of it's run than the beginning.
