I'm upset with those Japanese car manufacturer, they made us market for decade but stingy for the technology, dunno maybe our corrupt official made it too. Hope our future administration could make us independent and free from Nippon pressure on automotive.
This is not meant to defend Japanese companies, but they have practically just emerged in the defence export market in the last ten years or so and have only managed to sell or donate non-lethal items over the years.
I assume that this is due to the Japanese public's opinion, which is still largely against any form of arms exports or technologies that will be officially used for "offensive weapons."
Even with their participation in defence shows in the last few years, there are still obvious hesitations to discuss this openly. I know this because I have already spoken with them several times in the past and recently, so it seems that there is still a need to go the extra mile or use roundabout methods regarding this matter, as it remains a sensitive topic in Japan at least for the time being.
