My point is that having a military is not going to protect Japan from China or anyone. Nothing they build is going to check Chinese aggression in the region.
so, a nation has no right to at least try and protect itself? do you know how many PRC troops would break on the shores of japan? It would be like the Hot Gates all over again-- Persia had a huge army but they couldn't bring it all to bear on such a small point of attack at once. Same with attacking an island nation-the smaller the island the easier it is to fend off the attacker
Japan has a right to do this without our help.
and whatever the reason; if there is no other reason then it frees us up from our commitments there. do we really want to get in a war with walmart's base of manufacturing (the PRC) over japan-or any where else?
and, if it is useless to try to protect one's nation or oneself, then why own a gun? all those criminals out there are far more heavily armed and one person with a gun is not going to check their aggression.
