Emily Thornberry's review appears to be open-minded. That is at least what she is claiming, and the evidence from her recent media interviews and the direct conversations I have had with her lead me to believe it. She is suffering a relentless attack on her character and intelligence on the basis that she has no place in questioning the assertions of invulnerability of our systems. But this is doing disservice, to her, but far more importantly, to the issue facing us as a nation.
Trident is in the news again, and will continue to generate heat in the run up to a parliamentary debate promised later this year on the programme and patrolling posture. But the outcome is clear, pre-determined in the minds of the political elite and to some extent in contractual and diplomatic commitments.
