"Hope and Change" cause and effect...or not

"What's Going on Here?" [Victor Davis Hanson] (via NRO):

"Since January 2009, we have seen plenty of radical Islamists apprehended in the United States while planning mayhem on a massive scale, and even more violence committed by Islamic terrorists abroad in places like Afghanistan, Iraq, and Pakistan. Meanwhile, the Obama administration has been a) serially assuring the Muslim world (often literally amid explosions going off nearby) that we are atoning for and hitting the reset button on the insensitive and cowboyish Bush administration that fostered unnecessary tensions, b) making the case that a kinder and gentler United States is apologizing for 200 years of assorted sins, and c) assuring Americans that the days of unnecessary, Constitution-shredding anti-terrorism policies are over (albeit while quietly keeping intact the Patriot Act, intercepts, wiretaps, renditions, tribunals, etc.). Why, then, are these darn terrorists, whether domestic or foreign, not getting the new "hope and change" message? (Or are they?)
