It is so obvious from all this that we are almost identical to the chimps, as I've said elsewhere. "Them" and "us", torture, picking off the weakest, rape, murder. Some people assume that the only significant difference between us is our propensity for religion, but even there, it wouldn't surprise me if the chimps had some rudimentary superstitions.
I doubt Bush himself has the intellect to understand what is really happening, and I assume that his administration is actually run by the Vice-President and the Secretaries of State. They will have realised, as Margaret Thatcher did with the Falklands, that a war is a tremendous way of staying in power. If you can't increase your electorate's prosperity significantly, and you can't in a relatively static economy, then fear and nervous patriotism are your two best weapons.
Their problem is that their perception of war did not include defeat, and so they have absolutely no idea what to do, other than to keep plugging the fear element in order to stay in power. To that end, they desperately need Bin Laden to stay alive but untraceable, because he is the most wonderful bogeyman. Bin Laden needs Bush as well, which is why he seems to like releasing videos just before US elections, so that the rednecks will stay in power.
Blair ought to have had the brains to have seen the potential disaster, but he was too busy strutting around the international stage to notice, and he is far too proud and ambitious ever to admit any failing whatsoever. I stopped supporting Labour on the day we went to war.
The US and the UK will finally have to pull out of Iraq, sooner rather than later, and the only way they will be able to do so is by partitioning the country. That will leave three countries, for the Kurds, the Shi'ites and the Sunnis, with the last two remaining in a state of constant belligerence, because the oil is in the south, with the Shi'ites, whereas the Sunnis got used to ruling the whole shooting match, and don't want to relinquish control.
In the end, you can't blame anyone. People are apes, and they make all the same mistakes all the time. It is simply in our blood to be belligerent and often stupid. Posters to this forum may well be wiser and less aggressive than most, but it is neither wisdom nor peacefulness that leads to power.
