Tories: Disingenuous or fools over Renegotiation?

It appears that the Tory position will be to "renegotiate" over our EU status, but not to have a referendum or just repeal the ratification of Lisbon.

What would they do, what COULD they do in those negotiations? Lisbon is signed. Lisbon can self-amend. The EU can string out talks for 1, 2, 5 or 10 years. What can David Cameron do? What is his "walk away" position?

To get a proper renegotiation, one would need to have the ability and the will to adopt the "Nuclear Option" as in pull out of the EU entirely by repealing the 1972 Act. As no Parliament can bind its successors - and not forgetting that no MP nor Parliament is authorized to hand over sovereignty to foreign powers to begin with - the ability exists. The will is another mater. I am certain there is no will in the current leadership of the Tory Party.

While Dave is in interminable talks with EU filibusters in Brussels, the Tories will go merrily about their "own" (?) plans at deepening Regionalisation along the boundaries decided by the EU whilst the Commission will be self-amending the Treaty. For talks to work for the UK the EU needs a good reason to keep Dave at the negotiation table and to close a deal. They do not have one, nor, given the lack of sanction, do they NEED one.

The EU, I am certain, will not mind talking. Talk is cheap. They will listen to the demands then come back with a "compromise" that will gain favourable headlines but in fact concede nothing of any lasting power or value just as the "red lines" gained the UK nothing in reality.

We appear to be undergoing a ghastly "Bait and Switch" exercise with Labour and Conservatives hand in Fabian glove.

EDIT: I posted something similar to the above as a comment on this post over at Conservative Home. It was up last night but my comment did not see daylight. For shame, TimM, for shame.
