Iain Dale, who is now writing fortnightly for the Daily Telegraph, has an insightful column up today pointing out the mistakes David Cameron has made so far in his dealings with the US and suggesting that he needs to work hard to build bridges back to American politicians. Any hope of reconciliation with the current administration, Iain suggests, is gone. One question Iain does not raise is what this tells us about Cameron’s judgment. Was it a silly blunder, or a calculated decision to put electoral calculus before the special relationship? If the latter, did he assume the disruption would be permanent or merely temporary? Those are important questions the American politicians – whether Rudy, Mitt, Barack or Hillary – will need to ask when Dave reaches out to them. After all, if he is so quick to turn on the current President when things look bad, why would he not turn on them? Building trust back will require a lot of effort.
