What's impressive about Bane is that we're getting the definition of Bane as a Tactical Mastermind. Like a terrorist, he's hitting all of Gotham's weaknesses and is exploiting the very worse: he's a walking Hot & Cold War.
So far from my observation he's:
-Proven a threat to National Security for hijacking a plane and destroying it with passengers on board (not much to the effect of what I'm saying, but it plays along naturally)
-Somehow get's a hold and effects the Gotham Stock exchange (Economics)
-Exploits Harvey Dent's TRUE exploits to the public (Blackmail on Batman and Gordon/GPD)
-Manages to get a hold of such a deadly device that it blows up an ENTIRE football field
-Executes people in broad day light
-Manages to break into Wayne Enterprises and steals various Tumbler models (my guess with the help of Talia; possibly helps Bane get into the Stock Exchange as well, if run by Wayne Enterprises)
-And at last, gets into a show down with Batman to the degree of crippling him so that he can no longer be able to wear the cape and cowl again; and quite possibly sends him away and out of Gotham
The madman has practically planned out a full on WAR in Gotham: he's ruled out key people like Gordon and Batman who'll get in his way; exploited truths on Harvey Dent that makes the people of Gotham turn on higher authorities and loose faith because of a lie; pulverizes the stock exchange where money might as well be useless to everyone; and terrorizes the city after this madness by complete and utter destruction and death.
WE. ARE. *****ED. Don't know how Batman's going to win this one, seriously... can't stress it ENOUGH!
