I don't thrust anyone with a gun.
Same with the police my friend. I dont trust many people out there anyway but there are reasons why truck drivers and sales clerks at places have guns...its a tool like anything...a pencil could be used to kill people too >_> But i know you arent going to change your views.
The only reason i would see America defending Japan is if China ever attacked in which i dont think so unless provoked...but even then with all the provacations i seen lately China shouldnt and just should develop themselves internally first. But nyah whatever.
