I am not one who, to quote an American author, believes that democracy and enterprise have finally won the battle of ideas - that we have therefore arrived at the end of history, and there is nothing left to fight for. That would be unutterably complacent, indeed foolish. There will always be threats to freedom, not only from frontal assaults, but more insidiously by erosion from within.

If you set out to be liked, you will accomplish nothing.

We had to fight the enemy without in the Falklands. We always have to be aware of the enemy within, which is much more difficult to fight and more dangerous to liberty.

If you lead a country like Britain, a strong country, a country which has taken a lead in world affairs in good times and in bad, a country that is always reliable, then you have to have a touch of iron about you.

Socialists don't like ordinary people choosing, for they might not choose Socialism.

Rogue states never turn out to be quite the pariahs they are deemed. They are only able to cause, or at least threaten to cause, mayhem because they enjoy the covert support - usually by means of technology transfers - of one or more major powers within the charmed circle of global 'good guys'.

Adam Smith's 'invisible hand' is not above sudden, disturbing, movements. Since its inception, capitalism has known slumps and recessions, bubble and froth; no one has yet dis-invented the business cycle, and probably no one will; and what Schumpeter famously called the 'gales of creative destruction' still roar mightily from time to time. To lament these things is ultimately to lament the bracing blast of freedom itself.
