If I were a terrorist org with deep pockets, I'd just hire a black market deep see trawler with a sharp cable hook and have it drive north south a thousand miles out of Japan. Global everything shall halt.
Infrastructure damage that causes severe issues is such a low hanging fruit it's a mystery to me why it isn't attacked more by terrorist / anarchist / primitivist / et al. groups unless I adopt the Hansonian "X is not about seemingly related Y" viewpoint...
That's way too general and easily disprovable by any one of the single counterexamples of groups identified as bad people (whether or not the ones pointing fingers are also bad) blowing shit up or killing innocents. The Hansonian viewpoint is at least specific and offers predictions. (Here's a good overview: http://www.gwern.net/Terrorism%20is%20not%20about%20Terror)
If you want to make flippant statements, perhaps you should find or research an infographic like: "Civilian deaths due to extremist groups vs. civilian deaths due to US military actions and sanctions".
Feel free to ignore the far longer history of one side, and the fact one side gave weapons and stupid quantities of free media airtime to the other.
If you recall, Wikileaks' war logs proved once and for all the real quantity of civilian deaths is a lot higher than you hear reported in the media by outing the US military's internally reported stats.
More people probably died in the first two months of the year in multiple African conflicts than civilian deaths attributable to terrorism in the last 10 years.
PS. Funny how as soon as I post this reply I get downvoted on both comments. American nationalism is alive and kicking on HN :)
