As time goes by, the idea that this whole adventure was undertaken deliberately to destabilize Central/South Asia, so as to create a more or less permanent pretext for a US military presence there, becomes harder to resist.
It does indeed. I don't think Afghanistan was, but surely Iraq was? If we had only done Afghanistan, it wouldn't be enough influence in the region, would it?
The natural resources there are but one reason. Closing the pincers on Iran is another. To these I would add NATO encirclement of Russia and having a counterweight to burgeoning Chinese influence.
Remember Condoleeza Rice testifying in front of the Senate Committee that having Iraq as a democracy would be a 'stabilizing force' in the region?
On the domestic side, permanent war maintains the Military-Industrial-Congressional Complex, plus the prerogatives of the national security state against its own citizens.
