US plans attack on North Korea launch sites and inventory of rockets?

Telegraph:

America is drawing up plans for a “bloody nose” military attack on North Korea to stop its nuclear weapons programme, The Telegraph understands.

The White House has “dramatically” stepped up preparation for a military solution in recent months amid fears diplomacy is not working, well-placed sources said.

One option is destroying a launch site before it is used by the regime for a new missile test. Stockpiles of weapons could also be targeted.

The hope is that military force would show Kim Jong-un that America is “serious” about stopping further nuclear development and trigger negotiations.

Three sources - two former US officials familiar with current thinking and a third figure in the administration - confirmed military options were being worked up.

I suspect this is a leak designed to put more pressure on the North Korean leaders to negotiate.  The North Korean launch vehicles are vulnerable to this type of attack.  The regime is also having to deal with the collapse of its testing facility under a mountain caused by one of its nuclear tests. 

Since much of their current ill-gotten gain has been through cyber extortions it would seem reasonable to also cut off the North Korean access to the internet.
