You'd get less drive-by downvoting if you didn't say stupid things. Who knows, you might get less if you didn't keep complaining about it.
(Trains can be much faster than buses, carry much bigger loads, and use less fuel to do so. They are not useless. If the trains you've got in the US at the moment seem useless, that would be because they've been very poorly invested in over the last several decades. Oh, and that $12.8 trillion, while it's certainly a terrifyingly large figure, is not directly comparable with what's being spent in Iraq, e.g. because much of it is not spending but guarantees of the form "if institution X collapses, you'll get back at least the first $Y it owes you", and much of the rest is loans. Even in the present economic climate, what you lend you're quite likely to get back, not to mention that you get paid interest on it while it's lent.)
