The Hilter card is an instant credibility killer. Hate to say it, because someday the guy in charge really COULD be a Hiltler. But as Ab said, is so overused it's usually an indication that someone has flown off the handle.
Obama is no Hitler. Frankly, he's not that competent. Internationally, I'm not liking what I'm seeing.
So far he's managed to stumble a little with our relations with England, by improperly recieving/respecting the PM. Subtle example - that's not significant on it's face, but an indicator: The PM gave Obama a wooden pen and box, made from the wood of an English warship used to combat the slave trade in the Atlantic. Obama gave the PM a few Hollywood DVD's - that anyone could get at the corner store. When an English staffer commented to an Obama staffer that the reception overall was less than they typically expect, the response was: What makes you think England is so special? We've got 190 countries to recieve here. Nice.
He's doing a poor job with India - another HUGE US ally, by putting the brakes on the delivery of a bought and paid for warship. Because Pakistan doesn't approve. Again, great way to piss off your firends for no gain.
I've been trying to refrain from constantly bitching about the guy, as I don't want to be one of those hateful type people. Unfortunatly, I'm continuing to wait for signs of competency to lead a nation.
