1) An ad hominem defense is just as silly as an ad hominem attaxk. A JD won't save you from a logical fallacy. You said that because the PCA conditionally accepted the possible existence of the Kingdom of Hawaii, it therefor proves the existence of the Kingdom of Hawaii. This is just illogical, which I pointed out. 

2) you mention the 1928 (which is technically *after* 1898) Kellogg-Briand Pact: funny that I don't see the Kingdom of Hawaii among the signatories. 

3) existence is not default. Non-existence is the default state of reality. The Kingdom must actually exist in order to exist and cannot be assumed to exist.
