The battles the US military is engaged in involve hearts and minds, and drones are very bad from that perspective.

What you say is obviously true, but this shallow truth is shrouding the much more profound one that if you want to win "hearts and minds" you don't wage war in the first place.

... it is perfectly acceptable in polite society, politics and academia these days to demonize all Israelis without considering individuals

It's a pity you had to spoil your informative, insightful and interesting post with this stupid sweeping generalisation (which, ironically, accuses of making a stupid, sweeping generalisation).

Thanks for your post anyway.

It makes me really appreciate the Founders of the US. There were so many opportunities to turn this country into another Western Hemisphere dictatorship shithole and they didn't.

The irony being that the USA turned a lot of other countries into Western Hemisphere dictatorship shitholes. For example, Cuba, before Castro and his cronies 'liberated' it.

2) Untrue: a 44kHz *sampling rate* has a 44/2=22kHz Nyquist cutoff. Frequencies f>22kHz Nyquist limit "wrap around" to f-22kHz difference frequencies.

No matter how much you repeat this, it's not true. Look it up in any textbook.

Also, your allegations about the DFT allowing a perfectly sharp cutoff aren't realistic. A perfectly sharp cutoff implies an infinitely steep transition between passband and stopband, and this can only be achieved with an infinite number of points in the DFT.

a 25kHz tone sampled at 44kHz results in a spurious, highly audible (25-44/2)=3kHz aliasing signal

As another poster already said, no, it would result in a 19 kHz tone.

And this tone would not be audible, let alone highly audible, because the A/D conversion filter blocks frequency content above half the sample rate very effectively. (Unless you're using broken converters.)
