Indeed, I did not perceive his post as sarcastic - over-the-top though it may have been - since I have experienced first-hand similar sentiment being expressed with equal viciousness by others who most definitely were
not being sarcastic. Without an accompanying emoticon (whose rise in popularity is precisely because of situations like this), it's near-impossible to tell if someone online is being sarcastic or not purely from their written words. Tone of voice and body language are vastly underrated.
What a mess...
My apologies, my ill-formulated point.... *snip*
Apology accepted; glad to hear it was a misunderstanding after all... and I'm personally glad I didn't write certain choice words I was tempted to use...

Dragging this back on topic..
I heard a few years back (don't know if it's true or not) that we (Israel) have anti-missile interception systems that use (presumably) hypersonic velocity missiles, capable of intercepting and destroying a target missile before it leaves the airspace of the country it was launched from.
