Fading lion living in vicarious fantasy. China is about to be in a position to do whatever the fuck it wants and nobody will hit its mainland for the same reasons you think the US has been safe from attack.
Bla bla bla.
America has operated on the basis that the people it attacks don't have the reach to hit it.
FYI Everyone knows Japan has nuclear materials and if it does not have could make bombs in months. Been that way a long time. Your secret knowledge is rubbish. But it also can't take a hit. So proxy fighting again.
