That is simply not true. For the past couple of years the US military have been busy deposing various dictators (some of them renegade CIA puppets, to be sure) - but has not posed any threat to a legitimate nation. I do not think that most nations will loose much sleep over the possibility of being invaded by the US. That includes even Cuba - the US forces can easily launch a successful invasion of this country without encountering much resistance and without suffering any serious political consequences.
The worst thing about the Bush foreign policy is its self-righteous sanctimony and arrogance, which makes me nauseous, but it apparently appeals to the flag waving "God-bless-Amerika" "I-love-my-country-but-I-cannot-pay-my-bills" crowd.
