You think he did bad in London? Here is Mitt Romney's day's work in Israel:
He told the Arabs that they have an inferior culture, and at the same time praised Jews for having so much money- thus managing to commit an almost unheard of two-for-one act of antisemitism in one remark, as well asrendering any effort he might make as President to deal with Arabs virtually impossible.
Of course, since he seems to have no interest in Arabs except to bomb them, maybe conducting himself like a smug, self-righteous ass talking to his inferiors is his idea of masterful foreign policy.
He stated that, if President, he would make it U.S. policy that an undivided Jerusalem is the capital of Israel- something that no previous President, Democrat or Republican has ever done, because that act would produce not one shred of positive outcome, while needlessly antagonizing Arabs, solely to pander to his "base" on the right in this country- a miserable sign of what kind of foreign policy he would run. It also indicates his utter ignorance of the geographical and political realities of Jerusalem and East Jerusalem.
He has stated his support of Israeli attacks on Iran, a nearly unforgivable undermining of Obama's foreign policy efforts, in order to engage in one more violent right wing fantasy.
He has implicitly criticizes Obama's policy while he is abroad, something that is normally considered beyond the pale for Presidential candidates.
These are the acts of a man that is utterly unsuitable to have any substantive role in running our country. And yet, the press will let this all pass as though nothing much has happened. It is hard to believe that the Republicans could have found, in one man, someone worse that the whole Bush administration, but here he is. The United States as we know it will not survive his Presidency.
