And unlikely pair, but so argues Henry Porter in the Guardian:
There is a striking likeness in the expressions of George W Bush and Mahmoud Ahmadinejad of Iran as they confront each other over the issues of uranium enrichment and dominance in the Middle East. It falls somewhere between the chastened and defiant playground bully.
This is unsurprising: though not political equivalents, the two are really quite similar. Both had little experience of government or international affairs before being carried to power on a tide of populist, religious conservatism. Neither travelled abroad much, but they both had certain views about the world and the destiny of their nations. They had all the answers, yet there was also a dangerous lack of seriousness in them which has now earned them both the scorn of their people and rebuffs from their elders.
A fascinating analysis of fanaticism and failure, well worth a read.
