The Obama foreign policy, in broad strokes, has been a disaster.

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.

Ideas matter. Legislative proposals matter. Slick campaigns and dazzling speeches can work for a while, but the magic always wears off.

There are cycles in American politics. US cycles are even more pronounced because we Americans have a totally entrepreneurial presidential system. We don't have parliamentary opposition parties with a shadow prime minister and shadow cabinets. Every four years, the opposition reinvents itself.

This is a formidable enemy. To dismiss it as a bunch of 'cowards' perpetuating 'senseless acts of violence' is complacent nonsense. People willing to kill thousands of innocents while they kill themselves are not cowards. They are deadly vicious warriors and need to be treated as such.

If we insist that public life be reserved for those whose personal history is pristine, we are not going to get paragons of virtue running our affairs. We will get the very rich, who contract out the messy things in life the very dull, who have nothing to hide and nothing to show and the very devious, expert at covering their tracks and ambitious enough to risk their discovery.

The great divide in American foreign policy thinking is between those who believe in paper and those who believe in power.
