That might be what they say, but actions speak louder--for instance, indiscriminately publishing gigabytes of diplomatic cables, most of which are inconsequential.
Also, I'm pretty sure any secret that would have had strategic importance in WWII was of "political significance".
The cables were selectively published until the point that the encryption keys were disclosed. There was a front page story every week at least for several weeks.
Locations of radar installations have no political significance in themselves. Obviously where exactly the line should be drawn is up for debate but I see no one claiming the line is where you say they are claiming it is.
"Wikileaks will accept restricted or censored material of political, ethical, diplomatic or historical significance."
Most of your examples clearly don't meet that criteria and it would be a stretch for any of them.
