Aussie Submarine Battle: Correct Conclusion despite faulty Analysis

UPDATE #1   22 NOV 14 - "Magnitude-6.7 quake injures at least 41 in Nagano" Japan Times
"...no abnormalities were immediately apparent at its gigantic Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture. The plant, the largest atomic energy complex in the world, has remained offline since the Great East Japan Earthquake of March 2011" [color emphasis mine].


Background
The Australian defence industry says it is "terribly confused" about the multi-billion-dollar submarine project, with reports the Federal Government is considering buying eight submarines from Japan.  SOURCE

Looming, Unmentioned Problems in Japanese Sourcing of Aussie Subs


Unpredictable Political Upheavals - Flagrant Example:  On 3 September 2014, French President François Hollande halted delivery of the first warship, the Vladivostok, to Russia.

Unpredictable Natural Disasters - Flagrant Example:  On Friday 11 March 2011, Japan was hit by a tsunami triggered in a magnitude 9.0 (Tōhoku) earthquake.  Not only was Japan's Fukushima Daiichi nuclear plant devestated, Japanese ability to export repair parts and OEM equipment suffered mightily. Resulting supply chain impairments caused Japan to post its first annual trade deficit in 30 years.

The Japanese nation has had a long history of earthquakes and seismic activity. Japan lies in an area of high seismicity located near major tectonic plate boundaries situated on the "Pacific Ring of Fire".

Submarines are always silent and strange.
