If no commentators have noted, or perhaps even noticed, this new spin on American military policy, it may be because they don't take Bush's unscripted remarks seriously. (It's just Bush, talking off the top of his head. No sense parsing the implications.) That in itself is quite a commentary on this president. But it's not clear that these particular remarks were unscripted. Bush used the same phrase—"a capacity to make a weapon"—three times; it was almost certainly a part of his brief. Either the statement means something—that we now reserve the right to wage pre-emptive war on a hostile power that has the mere capacity to make weapons of mass destruction—or it's empty blather. It's unclear which would be more unsettling.
