I don't find anything in that column which calls Bush stupid--unless you feel referring to his Christanity means that.
Here is a section that sets out the theme of the stupid, inexperienced Bush:
In contrast, they show how George W. Bush is "bound to Israel by a strong religious faith molded by his convictions as a born-again Christian." He described his visit to Israel in 1998, one of his few visits abroad in his pre-presidential life, as "an incredible experience." He met with Gen. Ariel Sharon, apparently unaware of the man's shadowy past, and the two hit it off immediately; in fact, that encounter was an experience that has caused him to side without exercising even minimal judgment with Sharon, no matter what he does.
It should not be missed that the president was on that same trip miffed and insulted when Yasser Arafat, with his usual incompetence, refused to meet with the then-Texas governor, who was already a presidential candidate-in-waiting.
One begins to uncover a pattern here: A major clue to the president's thinking on foreign policy is his strong tendency to focus only on what he has himself seen and done. This is also true of his effusive relationship with Mexico, with which he feels comfortable because of his experience as governor of Texas.
Foreign policy by personal comfort level? "Unlike his father's vast diplomatic and government experience, the current president's philosophy toward Israel is based largely on personal experience," The Wall Street Journal Europe article averred, "and his relationships -- and grudges -- now are helping to shape his administration's policies."
The passage, and the rest of the column, is fatuous manure.
