Why does Japan suck so much compared to China?
Subtle seems like suck until you are reminded it allows them to repeat Pearl Harbor upon your person. Somebody like you had two radar tech's reporting a large body of aircraft approaching the US Armed Forces. The radar people were then told what to do: FORGET ABOUT IT.
Advertising you dislike for any country versus another is not going to be a way to make friends, unless you are only interested in becoming friends with prejudiced people.
