On 23rd of September, Nikkei Newspaper reported that cyber attacks frighten many nations such as USA, Korea, France, Israel etc. It's so called 5th dimension war field.
I have been telling at various occasions that physical weapons would have less power in the future battles but growing professionals to do/protect cyber attacking would be more important for nations since the most of important systems are controlled by ICT technologies and cyber attack should be faster than physical weapons launched.
In Japan, Ministry of Defense has only just started planning to set up Cyber Defense Troops. We need to watch how Democratic Party plans.
