Do you agreed that South Korean navy is weaker then the JSDF? What do you see the JSDF do to the South Korean when these South Korean seiged the disputed rock island between Korea and Japan?
NADAAA! Big NOTHING! Yep, these Jap JSDF doing nothing to the South Korean.
How about the case of Northern Japan, where these Russian continue to occupied and hold four of their Japanese Island since end of WWII.
What are your mighty JSDF doing to Russia? NADDAAAAA! Big NOTHING again!
Spare me this mighty Jap navy talk! If PLAN is now preparing to face down the American Navy over Taiwan, you thinks the PLAN can't deal with a tiny Japan? You must agreed that American Navy is stronger then JSDF.
If PLAN is to fight American Navy, you think China can't deal with Japan Navy? You must be joking me.
