@Woodstock -
You seem to have a greater grasp of how things are "supposed" to be done in Washington than the typical American citizen (which probably explains much...)
Politics being what it is, I'd not be surprised if a number of measures now proving unpopular were done as one half of a concession for something-or-other.
WRT Iraq - we still haven't learned the lessons offered in Korea and Vietnam. The principal difference in Iraq & Afghanistan? The motivation is not political - it is religious. Secondary difference? We can forget about peace talks - it's a war of annihilation. Radical Islam has come out and decried us as the "Last Great Satan," and they will be satisfied with nothing less than the destruction of America (or overtaking with a predominantly Muslim/Islam populace - which is what's happening around you. Demographic warfare. We're already dealing with it with New Aztlan & the Reconquistas.)
Demographic warfare is the most recent change - the last large change in warfare was the conflict against a highly motivated and populous indigenous enemy, who had effectively unlimited manpower (thanks to overpopulation) and didn't mind throwing human waves against us. In Vietnam, it was often said that losing fifty VC to kill one American soldier was a net victory for the VC - and there is some truth to that.
Unfortunately, most of higher-higher is still fighting World War II. And, until we can fully grasp the change (moving toward small, highly mobile units in the field taking the fight to the enemy in their own backyard.) We have the assets to start doing this, but our political leadership lacks the will to use them effectively. Until this changes, we are doomed to loss.
And maybe Europe does have much higher tax brackets, but there are two factors at work there:
1) Much of Europe approaches socialism, from what I've seen.
2) Europe does, however, seem to do a better job of pushing tax dollars into social infrastructure. I'm quite sure there is a fair share of "pork barrel" politicking going on, but it's not as great as it is here.
(These two are in no particular order.)
WRT Politicians being "puppets" - don't leave that just at Bush I or Bush II (or any other POTUS) - effectively, all elected "leaders" are puppets of various special interest groups, lobbyists, and they're working to enrich their own egos or their own wallets.
"Democracy is based upon the idea that the public at large knows what sort of government they want, and deserve to get it good and hard." -H. L. Mencken. I'm sure I'm misquoting that, but the sentiment is there.
