) -- President Obama picked a bad time to start a fight with China. Not that there's ever a good time for a battle with the nation that buys most of our national debt and supplies most of the inexpensive goods U.S. consumers crave.

Why are we so worried about U.S. tire makers, anyway? Let's face it: The tire industry ain't what it used to be. We're pretty much down to

I know the president is worried about jobs, with something like 5,000 positions lost in the U.S. tire industry over the past five years. But those jobs were being sent to cheaper production locations overseas with or without the influence of Chinese imports. A temporary tariff isn't going to suddenly change that trend.

Ask any economist and you'll be told that tariffs ultimately cost more jobs than they save. It's a global world, and free trade is the best way to raise the tide for all the ships.

The president seems to be letting his need to garner union support for his health care agenda dictate U.S. international policy. It's unfortunate that Obama feels the need to play this card. This tire tussle is bad for U.S. consumers and U.S. companies alike. This is just what we


need as our economy begins to work out of the recession.

The Chinese are too important to trifle with, especially since they are financing our banking bailout and economic stimulus efforts by purchasing U.S. government debt.

We also have to bear in mind that U.S. companies need access to the Chinese market as badly as the Chinese want access to the U.S. market.

Chicken exporters and the U.S. auto industry may now find China closed to their products as retaliation. That's bad news for

Let's hope that Obama is ready to back down under international pressure. Having made the grandstand gesture to show his support for the unions, he may get "points for trying" that will help his health care agenda without killing the recovery.

I hate to say it, but the U.S. can't win an economic war with China.
