Impeachment may be the only solution

Kagro X at Daily Kos has an interesting exposition of what happens if Bush orders his troops to ignore subpoenas. Apparently, it's up to the DOJ to prosecute once a contempt of Congress motion has been passed. Last time that happened, in the Reagan administration (surprise, surprise), the DOJ refused to prosecute. Congress took the case to the Courts. The Court dismissed the case on the grounds that political disputes should be resolved by the politicians, not the Courts. The Reagan administration declared victory and no prosecutions were brought.

That certainly seems likely to repeat itself here.

And, that leaves impeachment as the only viable solution.
