And, Octavious, you are assuming that an "American Left" encompasses the ideals of the party that claims to be Leftist, namely, the Democrats.
It is entirely possible for an American to incorporate other ideals and therefore have a Left composed of ideologies from the American and other perspectives, still titled the "American Left" as it pertains to decision-making and governing America.
An example being, to generalize, the American Theatre Community as a whole.
Generally, you'll find Americans who make their work and life's passion in theatre, so entrenched in European ideals, naturally (so many of the great playwrights coming from there, the Master Bard and Kyd and Ibsen and Beckett and Moliere and the like... though in defense of the American scene, we DID have at least three greats in Tennessee Williams, Arthur miller, and Thornton Wilder) that there IS some influence. Likewise with those that practice philosophy here (and I don't mean take a class in Ethics just to become a nurse, like nearly the rest of my class does, I mean REALLY study and debate and attempt to reason and listen to lectures and question and even teaching and writing those ideas you synthesize) are inevitably incluenced by the ideas of Kant, Locke, Mill, Nietzsche, Aristotle (who I'm reading currently, his "Politics), Hume (just finished reading him and his "Enquiry"), Plato, Deescartes (reading him after Aristotle) Camus, Satre, Russell, and plenty more...
You'll find the few Americans, Octavious, who don't spend all day long staring at the idiot box (not even that TV itself is bad, but TV TODAY IS) or texting all day or stuck in a dead end job...
Those few, maybe 2%, but still there, Americans who READ and go to plays and listen to music that ISN'T all about rape and beating women and blasting with no rhythym whatsoever...
They're out there... and they're very much different than your conception of Americans as being overly Right and overly agressive or conservative, or both.
For instance, me myself, the political ideologies I work off of (and I'd be curious to here those of the rest of you in relation to your country, see what constitutes YOUR idea of an "English" Left vs. a "French" Left vs. an "American" Left, and the Right, and so on) are based off of, mainly, the synthesized ideas of John Stuart Mill and Aristotle.
That is a tad contrary, but essentially I like the GENERAL idea of Mill's leanings (not even going so far into Utilitarianism, but the idea of freedom of action and situational as opposed to rigid, coinstitutional thinking, THAT I love, and also hsi insistance that all classes should have a right to education and from THAT, from the strengths of one after a fair and equal education, THEN differences emerge, hopefully for the better, but even so, all are equal before that.)
Aristotle's insistance on diversity-over-conformity, essentially dispelling Plato's notion that the more those in the State are one and alike, the more harmonious and the better, that notion, too, I like.
Taken together, generally, I look at every situation from a previous framework, in this case, law and logic and the Constitution, but if I believe there's a greter chance for gain for the nation (and a HUGELY greater gain, and a SIGNIFICANT gain) then I'll consider that the previous laws, perhaps, are wrong, must be changed, or even violated given the circumstance. An example- abolishing slavery. THAT would e an example of violating and changing the law of the land for a FAR greater good, treating human beings like... human beings. Now, invading a country for OIL (not that I am saying Bush did, I am inclined to believe while he had an agenda in invading Iraq oil was not a part of it, at least not topping the list) would NOT meat that requirement, as it sets a bad precendent, and the good yielded (the theoretical oil) is outweighted by the vast badness (ie, a war, many dead... basically Iraq as it's turned out.)
On the whole, I believe we should operate in the Mill/Aristotle compromise politically and internationally. That is, we should treat all nations as equal and listen to them (Mill) but not at all be afraid to be one of the LEADING voices (notice, fair Europeans, I said LEADING and not the SOLE voice or the DOMINANT voice; American/England/Russia/China/Japan are all immensely powerful either militarily or economically, and have loud voices, and therefore its fair they should ahve the greatest clout. Nations like Saudi Arabia, France, Germany, Venezuela, Cuba, Iran, Israel, North Korea- all, too, have great stengths and goods to bring to an international Diplomacy table, and so they, too, get the lion's share of the attention and the most clout in international politics. Nations like Chad and Laos, I'm afraid, don't have the same amount of power, so, says Aristotle, they must be somewhat subject to the whims of the bigger nations, asn a Laos will not be able to defeat a China; however, says Mill, that doesn't mean they shouldn't ahve SOME voice, and shouldn't have the opportunity to GROW and GAIN more clout. That's my personal balance- stength should be rewarded, but no one nation or two nations should EVER be the only voices that "matter." The top 10-15 nations in the world militarily and economically should, therefore, be rewarded with a greater share of goods and more voice in affairs, but the smaller, weaker nations should not be destroyed or accosted, and must both be given a voice, alebeit a weaker one, and the chance to grow so they might join that "Top 15 Powers Club.")
That doesn't sound too American Right to me or Right to me... it sounds Center in some parts, and Left in others; the one part it is Right is the Powerful-over-Weak area, but as I allow for the WEak to become the Powerful, I see no problem in rewarding countries who are more successful with more clout and influence.
And, in any case, I'm not saying "Fuck everyone, this is AMERICA, we won WWII all by ourselves, totally, no one else helped at all, and we have nukes, so shut up or we'll nuke you!"
