It's pretty easy for a high tech power like the USA (and Britain) to defeat the professional standing armies and air forces of a low tech 3rd World opponent. It is not so easy to deal with the occupation of their land and the guerrilla insurgency that inevitably follows.

The Russians found that out in Afghanistan. The Americans are in the process of finding it out, one body bag at a time.

When Hitler would get bogged down in one insoluble situation...like the standoff at the English channel...he would relieve the frustration by launching a new glorious attack somewhere else...like Yugoslavia, Greece, North Africa...Russia!

I am worried that Bush will resort to the same sort of unthinking "let's find a new quick victory" agenda. The end result of such an expanding agenda is usually a very large war with disastrous consequences for the fools who launched it. Quite possibly a world war. One can only get away with just so many unprovoked invasions before one runs out of credibility and friends once and for all.
