Canadians are North Americans. No slight against my cousins to the south in the US of A, but they seem to have appropriated the name ‘American’. I don’t know any Canadian who calls themselves an American, though some are called that…but I digress.
The first Korean war occured because of a policy speach which excluded S. Korea from the domain of interest of the US. Kim Il Krazybastard took that as a green light. Sounds similiar to the first Gulf War, again, an intimation was made that the US didn’t care about the fate of Kuwait.
The civilized world didn’t seem to care when a certain leader annexed Austria, then demanded the Sudentenland (sp?) of chechoslovokia (damn spelling and time constraints!). That certain leader didn’t think anything would then happen when he invaded Poland.
Telling a bully to go ahead and have at it with your acquiescence against an innocent victim is no way to pevent a nasty ending for the victim or to prevent further bullying. If Japan could not count on the US for defense then they would go nuclear, so would Taiwan and half a dozen other nations, at least! I for one would not feel safer with 20+ nuclear states hostile to one another.
