Kate:

Tis is daft as because one can not, with current technology or even currently imaginable technology, create and store anti-matter.

Not to mention the fact that a bit of deuterium and tritium are more than enough to destroy anything, anywhere, at any time. So inveting trillions of dollars into unproven technology just to accomplish the same thing is ... well daft.

So daft that even the US Military couldn't even be considering it.
