The Republican's dogged pursuit Clinton over Benghazi is driven by three things: a fairly thinly disguised hatred; the goal of scoring political advantage in the run up to the next general election; and a penchant for conspiracy theories that "there must be something there, if only we look hard enough" (which while almost certainly true of anyone except the odd saint, may in fact be slightly more likely in Clinton's case).
In discussing Britain's role in the toppling of Saddam Hussein, Tony Blair noted that he had believed the faulty intelligence about WMD. His interview was particularly interesting for several reasons. First, his tone was apologetic - indeed he actually said "I have to apologise", unusual for any politician, even retired ones - and despite his claim to to be immune to public opinion, it would appear that 10 years of vilification have left their mark. Second, his strongest justification for invading was the strengthening of ties with the US. Cementing the 'Special Relationship' seems to have trumped good planning.
He also pointed out that no one has come forward with a better policy; walking away hasn't worked (Iraq and Afghanistan), nor have air-strikes while avoiding boots on the ground (Libya), nor arming a handful of rebels (Syria). Of course a better post-regime change plan might have made the choice-set in Iraq less problematic, although things were handled better in Afghanistan and the situation there isn't altogether too rosy. But that may have as much to do with Pakistan's poor behaviour as with the post-Taliban Afghan administration.
Why is Trump is spending his fortune on a futile bid for the Republican nomination?
- He likes nothing more than fame and publicity and spending money to get it makes utilitarian sense
- This is an investment in the Trump brand that will pay off down the line in TV deal and book sales etc.
- He hopes to shift the terms of the debate, possibly towards issues he cares about such as immigration (though perhaps we'll never know what he really thinks - it may all be an act. Or it might not be, which is slightly more disturbing)
President Obama is much more popular abroad then he is at home. One explanation is his reluctance to project power though the use of force, which Republicans (and some Democrats) interpret as weakness and everyone else sees as blessed relief.
Putin has been roundly criticised for supporting the Assad regime in Syria. Yet he for one seems to have learnt the lessons of Iraq and Libya; that if you depose a dictator either you remain as a colonial power (or at least an enforcer) or chaos ensues which may well spill over outside the country's borders.
