Why?

Bit of a philosophical question. and almost any answer will send this thread winging it's way to Jet Blast! Never mind, here goes.
In egging on a bunch of freedom fighters or terrorists (dependent upon your point of view) to overthrow a tyranical dictator (Gadaffi) the "west" has reaped exactly what it sowed. Dead dictators nearly always leave vaccuums in their wake (witness Tito in Yugoslavia for example) and the result is nearly always in-fighting by factions, armed by heaven knows who (but usually perm any one from the USA, UK, France, Russia, China). One thing is a given; that is that the general population ends up no better, and usually a lot worse off.
Airports, ports, energy facilities and other important state infrastructure are always prime targets since if you destroy it (whatever "it" is) it stops an opposing faction using it.
Upside (for us in the developed world) is that when one side eventually wins the new government has to spend billions on reconstruction, normally with big global corporations and national governments.
And so it goes around.
That might appear a little cynical - but then I am.
