If fences don't work, why is there one around the White House.

Post-Watergate morality, by which anything left private is taken as presumptive evidence of wrongdoing.

Every new president flatters himself that he, kinder and gentler, is beginning the world anew. Yet, when Barack Obama in his inaugural address reached out to Muslims by saying, 'To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect,' his formulation was needlessly defensive and apologetic.

Obama's Democrats have become the part of no. Real cuts to federal budget? No. Entitlement reform? No. Tax reform? No. Breaking the corrupt and fiscally unsustainable symbiosis between public-sector unions and state governments? Hell no.

Somebody actually said that I'm the only entity on earth, other than rogue states, that has received an apology from the White House.

There's no free lunch. If you want an industrial economy, you need energy. If you want energy, it will produce pollution. You can have it in two forms. You can have it dissipated in the atmosphere - like carbon dioxide - which then you cannot recover, or you can have the waste concentrated in one small space like nuclear. That is far easier to deal with. The idea that you can be able to create renewable energy at a price anywhere near the current price for oil or gas or coal is a fantasy.

Where there is a confluence of interests among nations, as, for example the swine flu or polio, you can get well functioning international institutions like the World Health Organization. And you can act. Climate change is different, because the science remains hypothetical and the potential costs staggering.
